Acube-shaped container has an edge length of 12 in. the container is filled with smaller plastic cubes that each have an edge length of 3 in. how many cubes are needed to fill the container?

volume of container=123=(12)(12)(12)=1728volume of container=123=(12)(12)(12)=1728

The volume of the container is 1728 in³.

volume of a plastic cube=33=(3)(3)(3)=27volume of a plastic cube=33=(3)(3)(3)=27

The volume of one plastic cube is 27 in³.

number of cubes to fill container=1728÷27=64number of cubes to fill container=1728÷27=64

So 64 plastic cubes are needed to fill the container.
