If one face of a cube has an area of 16 m2, then what is the volume of the cube?
Answer:
64 m3
- Let us assume that the length of a side of the cube is a.
- The area of one face of the cube is 16 m2.
As the face of a cube is a square, its area = a2, where a is the side of the square(cube).
⇒ 16 = a2
⇒ 42 = a2
⇒ a = 4 m - Volume of the cube (V) = a3, where a is the side of the cube.
⇒ Volume of the cube = (4)3 = 4 × 4 × 4 = 64 m3 - Therefore, the volume of the cube is 64 m3.
