Indices Are Used in Area Problems to Show the Units Used Are Squared
Length x width = areaA pool is a rectangleLength = 30 ft.Width = 15 ft.
Area = 30 x 15 = 450 ft. 2
15ft.
30ft
Indices Are Used in Volume Problems to Show the Units Used Are Cubed
Length x width x height = volumeA box is a rectangleLength = 10 cm.Width = 10 cm.Height = 20 cm.
Volume = 20 x 10 x 10 = 2,000 cm.3
