2. 0-9: Volume
Volume: The space occupied by a solid. Volume is measured in cubic units.
The formula for the volume of a rectangular prism is V = l ● w ● h
The prism on the right has a volume of 2 ● 2 ● 3 = 12 cubic units

3. 0-9: Volume Find the volume of each rectangular prism
The length is 8 cm, the width is 1 cm, and the height is 5 cm
V = lwh
= (8)(1)(5)
= 40 cubic centimeters
The prism on the right
= (4)(2)(3)
= 24 cubic feet

4. 0-9: Volume
The volume of a solid is the area of the base multiplied by the height.
For a cylinder, the area of the base is πr2. So the volume is V = πr2h
The cylinder on the right has a volume of π(3)2(6) ≈ cubic inches

5. 0-9: Volume Find the volume of each cylinder
The radius is 5 cm, and the height is 6 cm
V = πr2h
= π(5)2(6)
≈ cubic centimeters

6. 0-10: Surface Area

7. 0-10: Surface Area
Surface Area: The sum of all the surfaces (faces) of a solid. Surface area is measured in square units.

8. 0-10: Surface Area
Find the surface area of each solid. Round to the nearest tenth if necessary
The prism has a length of 3 meters, width of 1 meter, and height of 5 meters
S = 2lw + 2lh + 2wh
= 2(3)(1) + 2(3)(5) + 2(1)(5) =
= 46 square meters

9. 0-10: Surface Area
Find the surface area of each solid. Round to the nearest tenth if necessary
The cylinder has a height of 8 cm and radius of 3 cm
S = 2πrh + 2πr2
= 2π(3)(8) + 2π(3)2
= 48π + 18π
≈ square centimeters
