Question

The expression 6x2 gives the surface area of a cube, and the expression x3 gives the volume of a cube, where x is the length of one side of the cube. Find the surface area and the volume of a cube with a side length of 4 meters.

Answer 1

surface area of the cube is 96m² and the volume is 64m³

Explanation:

Surface area of the cube = 6x²

x is the side length

Given

x = 4metres

Surface area of the cube = 6(4)²

Surface area of the cube = 6(16)

Surface area of the cube = 96m²

Volume of the cube = x³

Volume of the cube = 4³

Volume of the cube = 64m³

Hence the surface area of the cube is 96m² and the volume is 64m³
