A rectangular prism with a volume of 5 cubic units is filled with cubes with side lengths of 1/3 unit. How many 1/3 unit cubes does it take to fill the prism?

A cube with sides each 1/3 unit will have a volume of  (1/3)3  =  1/27  cubic units.

 

If you have a volume of  5  cubic units, then to find the equivalent amount of  cubes that each have a volume of 1/27 cubic units,

divide  5  by  1/27  =  5 x 27/1  =  135.
