Question

The expression 6x squared gives the surface area of a cube, and the expression x cubed gives the volume of a cube where x is one side of the cube. Find the surface area and the volume of a cube with a side length of 7 meters.

Answer 1

See below in bold.

Explanation:

Area of one face of the cube = 7^2 = 49 m^2.

Surface area = 6 * 49 = 294 m^2,

Volume = 7^3 = 343 m^3.
