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 2 meters.

Answer 1

Surface of a cube = S(x)

S(x)=6x²

S(2m)=6(2m)²=6(4m²)=24m²

The surface of this cube is 24m².

Volume of a cube = V(x)

V(x)=x³

V(2m)=(2m)³=8m³

The volume of this cube is 8m³ .
