$6b+bx=ax+a^2\implies 60-a^2+bx=ax\implies 60-a^2=ax-bx \\\\\\ \stackrel{\underset{\qquad \downarrow }{\textit{common factoring}}}{60-a^2=x(a-b)}\implies \cfrac{60-a^2}{a-b}=x$

A cube has a volume of 7 to the 3rd power cubic centimeters . what is its surface area?

cricket20 [7]

This cube has 6 faces, and all side lengths are equal.

The volume of a cube with sides of length L is given by L^3.

The problem says that the volume is 7^3, which means that each side is 7

The surface area of a cube of length L is 6*L^2. Since L = 7, the surface area is:

6*7^2 = 6*49 = 294 cm^2
