If total surface area of a cube is 384 cm2, then what is the volume of cube?
Answer & explanation
Correct answer: option 1
We know that,
The total surface area of a cube = 6a2
The volume of a cube = a3
We have,
The total surface area of a cube = 384 cm2.
According to the question,
6a2 = 384
= a2 = 64
= a = 8 cm
The volume of the cube = (8)3 = 512 cm3
