rectangular prism

Question

A rectangular prism has a volume of 520cm and a height of 20 cm. if one side of the base is 12 cm. how long is the other side?

Answer 1

520/(12)(20= 520/240 = 52/24 = 13/6 = 2 1/6 cm

= 2.1666...cm = about 2.17 cm

Volume = V= LWH = 520 = 12(20)W

W= width = 520/12(20) = 52/12(2) = 26/12 = 13/6 = 2 1/6 cm
