This document defines and provides formulas for calculating surface areas and volumes of various 3D shapes including cubes, cuboids, cylinders, cones, spheres, and hemispheres. It states that the total surface area of a cube is 6 times the area of one face, and the volume is the cube of the edge length. The total surface area of a cuboid is 2 times the sum of the area of the base and lateral faces, and the volume is length times breadth times height.

Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
Honest Reviews of Tim Han LMA Course Program.pptxtimhan337

3. DEFINATION:-A cuboid whose length ,breadth, height
are equal is called a cube.
SOLID CUBE:-A solid cube is the part of the space
enclosed by six faces of the cube.
4. A cube is a region of space formed by
six identical square faces joined along
their edges. Three edges join at each
corner to form a vertex.
5. SURFACE AREA OF CUBE: Since all six faces of a cube
are squares of the same size i.e. For a cube we have l=b=h.
Thus, if l cm is the length of edge or side or a cube , then
Therefore, surface area of a cube=6(a)square.
6. A solid which has six rectangular
faces at right angles to each
other.
7. Surface Area without theTop = 2 (bh + hl) + lb .
Surface Area withoutTop & Base = 2 (bh + hl).
Total Surface Area =2 (lb + bh + hl).
8. -T.S.A of a cube = 6a2.
-Lateral surface area of cube= 4(edge)sq.
-Volume of cube= (edge) cubic .
-T.S.A of a cuboid = 2(lb+bh+lh).
-L.S.A of a cuboid = 2 (l + b) h.
-Volume of the cuboid = lbh .
9. A cylinder is one of the most basic curvilinear geometric shapes, the
surface formed by the points at a fixed distance from a given line
segment, the axis of the cylinder.
The solid enclosed by this surface and by two planes perpendicular
to the axis is also called a cylinder.
10. TSA of a cylinder = area of the base + area of
top + CSA of the cylinder
= ∏r2 + ∏r2 + 2∏rh
= 2∏r2 + 2∏rh
= 2∏r(r + h)
Where, r is the radius
h is the height of the cylinder
11. Volume of the cylinder = area of the base x
height
= r2 x h
=∏r2h
Volume of hollow cylinder = ∏(R2 - r2) h
Where, r is the radius and h is the height
12. A cone is a three-dimensional geometric
shape that tapers smoothly from a flat base
(usually circular) to a point called the apex or
vertex.
13. TOTAL SURFACE AREA =curved surface area
+area of the base
= ∏rl+ ∏r2
+ = ∏r(r+l)
Curved surface area of cone =area of sector
=1/2 *l *(2 ∏r)
= ∏r l
14. 1.A sphere is a perfectly round geometrical object in three-dimensional space.
2. Hemisphere refers to the equal halves of the sphere and can also be called
the 3d design for a semi-circle.
15. When we talk about
painting or polishing the
surface it is related to the
surface area.
Surface-Area (TSA) = 4∏r2
Where,
‘r’ is the radius
from the center to surface.
16. When we talk about the air in the solid or
want to count the no. of small object from
the bigger one then it is related to the
volume.
Volume of the sphere = 4/3∏r3
Where, r is the radius.
17. TSA of hemisphere = 3∏r2
CSA of hemisphere = 2∏r2
Where, ‘r’ is the radius.
18. Volume of the Hemisphere = 2/3∏r3
Where, r is the radius.
