Answer 1

Explanation:

64 cubes

64 cubes with each side equaling 1 cm are required to make a 4cm cube

Answer 2

Answer:64 cubes

Volume of third cube = 8 × 8 × 8 = 512 cm³. => Then Volume of bigger cube = 512 + 1 + 216 = 729 cm³. => So, side of bigger cube (a) = ³√729 = 9 cm. => Surface area of cube = 6 × a² = 6 × 9 × 9 = 486 cm².
