The volume of a cube is 64cm
3
. The total surface area of the cube is:
- A16 cm²
- B64 cm²
- C96 cm²
- D128 cm²
Solution & Step-by-step Explanation
Let the side length of the cube be a.
The volume of a cube is given by V=a
3
.
a

=64⟹a=4cm
The total surface area (TSA) of a cube is given by the formula:
TSA=6a
2
TSA=6×(4)
