Question

If the smaller cube has a surface area of 384cm^2, what is the surface area of the larger cube?

Answer 1

smaller cube has 384 cm2, then any large cube area compare to it is greater then 384cm2

>384cm2

Answer 2

The surface area of the smaller cubes = 6 (12) = 6 cm2. Therefore, the surface area of 64 such cubes = 64 * 6 = 384 cm2. The surface area of the big (original) cube = 6(42) = 6*16 = 96 cm2.
