Question

The number of solid cubes of 1 cm that can be made by cutting a solid cube of side 4 cm = .

• A. 64
• B. 32
• C. 16
• D. 8

Answer 1

The correct option is A 64

The volume of a cube = (side)${}^3$.
The volume of a cube of side 4 cm = (4)${}^3$cm${}^3$ = 64 cm${}^3$.
The volume of a cube of side 1 cm = (1)${}^3$cm${}^3$ = 1 cm${}^3$.
Hence, The number of cubes of 1 cm that can be made by cutting a cube of side 4 cm = $\frac{64}{1}$ = 64.
