Answer:
Small cube: 4 feet
Large cube: 12 feet
Step-by-step explanation:
So, for the small cube, we know that side x side x side will equal 64, the volume.
4 x 4 x 4 = 64, so 4 is the side length for the small cube.
For the large cube, it is just the small side multiplied by 3.
So, 4 x 3 = 12, the length of the larger cube's side.
