This document provides information about measuring and calculating dimensions of 3D geometric shapes. It defines various 3D shapes like polyhedrons, prisms, pyramids, cylinders, cones and spheres. It also provides formulas to calculate the surface area and volume of these shapes. Surface area is defined as the total area of the outer surfaces, while volume is the space enclosed within the shape. Formulas are given for surface area of cubes, rectangular prisms, cylinders, cones, spheres and volume of rectangular prisms, triangular prisms, square pyramids, cylinders, cones and spheres.

1. 1
Measurement of Three-dimensional Figures
Polyhedron is a solid figure with no curved sides. It is bounded by polygons as its
surfaces. The flat surfaces from by polygons and their interior are called faces. Faces
intersect at line segments called edges. Two or more edges intersect at a point called
vertex.
The polygon at the left has 4
faces, 6 edges and 4 vertices. It
is called a tetrahedron

vertex
A Prism is a polyhedron whose
bases are congruent and parallel
and whose lateral faces are
parallelogram. The prism at the
left has 2 bases and 4 lateral
faces.

2. 2
A Pyramid is a polyhedron with a polygon as base and triangles as lateral faces.
The most common pyramids are those with triangles, square and, rectangles as bases.
A Cube is a regular prism
because it is bounded by a
regular polygon (square) and all
its angles are right angles.

A Rectangular solid is the most

A Cylinder is a solid whose bases are congruent circles. A right circular cylinder
is a cylinder whose altitude is perpendicular to the bases and has an endpoint in each
base.
A Cone is a solid with a circle as base and all line segments from the circle meet
at a point called the vertex. A right circular cone is a cone whose altitude is a segment
that is perpendicular to the base. Any segment that joins the vertex to a point on the circle
is a slant height.
A Sphere is a solid with all points of which are equidistant from the fixed point called the
centre. A radius of a sphere is a segment whose endpoints are the centre and a point on
the sphere. CD is a radius. A chord of a sphere is a segment whose endpoints are points
on the sphere. MN is a chord. A diameter of a sphere is a segment that contains the centre
and whose endpoints on the sphere. PR is a diameter. A tangent to a sphere is a line that
intersects the sphere in exactly one point. XY is a tangent to the sphere at O.

Measurements of 3D Figures
Surface Are of Solids is defined as the sum of the areas of the outer surfaces of a solid.
These outer faces are known as faces.
A. Surface Area of a Cube. To find the surface area of a cube, multiply the square f
the length of a side by 6.
B. Surface Area of Rectangular Prism is the total area of the surfaces of rectangular
prism.
Formula;
SA = 6s2
Where s is the side or the edge of the cube
Example;
1. s = 2.2cm
SA = 6s2
= 6(2.2cm) 2
= 6(4.84cm2)
SA = 29.04cm2
2. s = 0.09m
SA = 6s2
= 6(0.09cm)2
= 6(0.0081m2)
SA = 0.0486m2
Formula:
SA = 2B + LA
where B is the area of the base
LA is the area of the lateral faces
Examples:
1. Find the surface area of a rectangular prism whose length is 7cm,
width is 4cm and thickness is 5cm.
SA = 2B + LA
SA = 2(lw + lh + wh)
= 2[(7cm)(4cm) + (4cm)(5cm) + (7cm)(5cm)]
= 2(28cm2 + 20cm2 + 35cm2)
= 2(83cm2)
SA = 166cm2
2. L = 12cm, w =7cm and h = 6cm
SA = 2B + LA
SA = 2(lw + lh + wh)
= 2(12cm x 7cm) + 2(7cm x 6cm) + 2(12cm x 6cm)
= 168cm2 + 84cm2 + 144cm2
SA = 396cm2

5. 5
C. Surface Area of Cylinder is the amount of spaces outside the sphere.
D. Surface Area of a Cone is the amount of space outside the cone.
E. Surface Area of Sphere is the amount of space outside the sphere.
Formula;
SA = 2Лr2 + 2Лrh or SA = 2Лr(r + h)
where r is the radius
h is the height
Example:
1. Find the surface are of a cylinder having radius is equal to 7cm and
height is 20m.
SA = 2Лr2 + 2Лrh
= 2(3.14) (5cm)2 + 2(3.14)(5cm)(20cm)
= 2(3.14) (25cm2) + 2(3.14)(100cm2)
= (6.28) (25cm2) + (6.28) (100cm2)
= 157cm2 + 628cm2
SA = 785cm2
Formula:
SA = Лr2 + Лrs
where s is the slant height
and r is the radius of the base
Example:
1. Find the surface area of a cone having s = 7.25cm and r = 3.5cm.
SA = Лr2 + Лrs
= (3.14) (3.5cm)2 + (3.14) (3.5cm) (7.25cm)
= (3.14) (12.25cm2) + (10.99cm2) (7.25)
= 38.465cm2 + 79.6775cm2
SA = 118.1425cm2
Formula:
SA = 4Лr2
where r is the radius
Example:
1. Find the surface area of a sphere having r = 6cm.
SA = 4Лr2
= 4(3.14) (6cm)2
= 12.56 (36cm2)
SA = 452.16cm2

6. 6
F. Surface Area of Square Pyramid is the amount of space outside the square
pyramid.
Volume is used to measure space. It is the amount of space enclosed in a solid figure. It is
expressed in cubic denominations.
G. Volume of a Rectangular Prism is the amount of space enclosed in rectangular
prism.
Formula:
SA = s2 + 2bs
where s2 is the area of the base
b side of the base
s is the slant height
Example:
1. Find the surface area of the square pyramid having b = 3cm, s = 5cm
and s2 = (3cm)2.
SA = s2 + 2bs
= (3cm)2 + 2(3cm)(5cm)
= 9cm2 + 30cm2
SA = 39cm2
Formula:
V = l x w x h or area of the base times height SA = B x h
where l is the length
w is the width
h is the height
Example:
1. Find the length of the rectangular prism having l = 4.2cm, w = 3.7cm
and h = 2.5cm.
V = l x w x h
= (4.2cm) (3.7cm) (2.5cm)
= 15.54cm2 (2.5cm)
V = 38.85cm3

7. 7
H. Volume of Triangular Prism is the amount of space enclosed in triangular prism.
I. Volume of Square a Pyramid is the amount of space enclosed in a square
pyramid.
Formula:
V = bh x H
2
Where b is the length of one side of the base
h is the height of the altitude triangular prism
H is the height of the base
Example:
1. Find the volume of triangular prism having l = 3.4cm, b = 3cm and h =
3.2cm.
V = bh x H
2
= (3.4cm) (3.2cm) x 3cm
2
= 10.88cm2 x 3cm
2
= 5.44cm2 x 3cm
V = 16.32cm3
Formula:
V = 1 (l x w) h
3
Where l is the length
w is the width
h is the height
Example:
1. Find the volume of a pyramid having l = 9cm, w = 8cm and h = 7cm.
V = 1 (l x w) h
3
= 1 (8cm x 9cm) x 7cm
3
= 1 (72cm2) x 7cm
3
= 24cm2 x 7cm
V = 168cm2
In the case of square pyramid the length and the width are equal.

8. 8
J. Volume of a Cylinder is the amount of space enclosed in a cylinder.
K. Volume of a Cone is the amount of space enclosed in a cone.
L. Volume of a Sphere is the amount of space enclosed in a sphere.
Formula:
V = Лr2h
Where is the height
Example:
1. Find the volume of a cylinder having r = 3cm and h = 10cm.
V = Лr2h
= (3.14) (3cm)2 (10cm)
= (3.14) (90cm3)
V= 282.6cm3
Formula:
V = 1 Лr2h
3
Where r is the radius
h is the height
Example:
1. Find the surface area of a cone having the r = 3cm and h = 6cm.
V = 1 Лr2h
3
= 1 (3.14) (3cm)2 (6cm)
3
= 1 (3.14) (9cm2) (6cm)
3
= 1 (3.14) (54cm3)
3
= 169.56cm3
3
V = 56.52cm3
Formula:
V = 4Лr3
3
Example:
1. Find the volume of a sphere having h = 0.9cm.
V = 4Лr3
3
= 4 (3.14) (0.9cm)3
3
V = 3.05cm3
