Question

The surface area (SA) of a cube with a as the length of each of its sides is given by the formula . If the surface area is known, how can you rewrite the formula to find its side?

Answer 1

Explanation:

1 surface area of the cube is s*s.

There are 6 faces on such a cube.

Area = 6*s^2 Divide by 6

Area/6 = 6s^2 / 6 Do the divsion

Area/6 = s^2

s = sqrt(area/6)
