A rectangular prism with a volume of 4 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?

Answer 1

Hi Jas, this is not a Series 6 question, but I will walk you through the question nevertheless. The volume of a cube is side length cubed since all of the sides are of equal length. Volume in this case will be 1/27 cubic units. So you would need 27 of these cubes to fill out 1 cubic unit. You are looking for 4 cubic units so 4*27=108 cubes to fill the prism
