1. Volume of Rectangular Prisms
Objective: To develop and use a formula for the volume of a rectangular prism

2. What is volume?
The volume of a solid object such as a brick or a ball is a measure of how much space the object takes up. The volume of a container such as a box is a measure of how much the container will hold.

3. Volume Volume – the amount of space occupied by an object. Example:
The VOLUME of this cube is all the space contained by the sides of the cube, measured in cube units (units3). h w l

5. Volume Volume – the amount of space occupied by an object. Example:
The VOLUME of this cube is all the space contained by the sides of the cube, measured in cube units (units3). h w l

6. Example: The AREA of the base of this rectangular prism is l x w.
Volume
Volume – To calculate the volume of a prism, we first need to calculate the area of the BASE of the prism.
Example: The AREA of the base of this rectangular prism is l x w. h w l

7. Volume We find that: Volume = (l x w) x h
Volume – Once we know the area of the base, this is then multiplied by the height to determine the VOLUME of the prism.
We find that:
Volume = Area of Base x Height
Volume = (l x w) x h h w l

8. Volume (Rectangular Prism)
Formula:
V = l x w x h
= - cubic. unit h w l

9. Volume Find the volume of this prism… Formula: V = l x w x h
= 7 x 5 x 4
= cubic. cm
7 cm
4 cm
5 cm

10. Volume Formula: V = l x w x h = 6 x 5 x 8 = 240 cubic. cm
Find the volume of this prism…
Formula:
V = l x w x h
= 6 x 5 x 8
= cubic. cm
8 cm
5cm
6 cm
