Volume

Rectangular Prisms and Cylinders

Rectangular Prism• The volume V of a rectangular prism is

the product of the length l, the width w, and the height h.

V = l(w)(h)• The volume of a three-dimensional figure is the measure of space it

occupies. • It is measured by cubic units– Ex: centimeters cubed (cm³) length

width

height

Example 1

• Find the volume of the rectangular prism.

5 cm4 cm

3 cmV = l(w)(h)V = 5(4)(3)V = 60 cm³

Cylinder

• The volume V of a cylinder is the area of the base times the height h.

V = (Area of the base)(height)• The base of a cylinder is a circle. • You will have to find the area of the

circle and multiply that by the height of the cylinder.

• It is measured by cubic units– Ex: centimeters cubed (cm³)

Example 2• Find the volume of the cylinder. Round your

answer to the nearest hundredth.
