• Objective To develop and use a formula for the
  volume of a rectangular prism

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.

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).

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.

Volume

• 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
