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

  21. Indices Are Used in Volume Problems to Show the Units Used 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. 20 10 10 3

  22. Here Are Some AreasChange The Units To Indices 2 40 cm squared = 40 cm. 56 sq. m = 56 m. 38 m. squared = 38 m. 56 sq. mm. = 56 mm. 2 2 2

  23. Here Are Some VolumesChange The Units To Indices 3 30 km cubed = 30 km. 26 cu. mm = 26 mm. 44 m. cubed = 44 m. 56 cu. cm. = 56 cm. 3 3 3
