Exponents Are Often Used in
Area Problems to Show the
Feet Are Squared
Length x width = area
A pool is a rectangle
Length = 30 ft.
Width = 15 ft.
Area = 30 x 15 = 450 ft.2
15ft.

Exponents Are Often Used in
Volume Problems to Show the
Centimeters Are Cubed
Length x width x height = volume
A box is a rectangle
Length = 10 cm.
Width = 10 cm.
Height = 20 cm.
Volume =
20 x 10 x 10 = 2,000 cm.
