volume and space formula

1. volume and surface areaMathematics Gr. 7

2. Prism
•Flat surface
•Parallel lines
•Same across sections
•NO CURVES

3. Regular Prisms
•Triangle
•Square
•Rectangular
•Penatgonal

4. Irregular Prism
•Different from regular prisms
•Irregular Pentagon

5. Formulas:
•Area = Area x Length
•Ex: A triangle has an area of 20 sq.
cm and 10 cm long.
•20 sq.cm x 10 cm = 200 cubic cm

6. Cubiod
•Box shape
•Rectangular prism
•Right angle

7. Square prism
•2 sides are equal
•Appearance of a square

8. Cube (Hexahedron)
•3 sides are equal
•Has a face of a square

9. •Note: The name "cuboid" comes from
"cube" and -oid (which means "similar to,
or resembling") and so says "it is like a
cube".
•Another use of -oid is when we talk
about the Earth being a spheroid (not
exactly a sphere, but close).

10. Formulas
Volume = L(W) (H)
Surface Area = 2(L)W) + 2 (W)H + 2 (L)H
