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?

number of cubes required to fill the rectangular prism = 108 unites

Step-by-step explanation:

Volume of rectangular prism = 4 units

Volume of cubes = A³ where A is the side length

Hence Volume of cube = (1/3)³ = 1/27 cubit units

Hence number of cubes required to fill the rectangular prism = 4 ÷ (1/27) = 108 unites
