Question

The surface area (SA) of a cube with a as the length of each of its sides is given by the formula SA = 6a^2 in the surface area is known, how can
you rewrite the formula to find its side?

Answer 1

Answer:

B

Step-by-step explanation:

A cube has 6 congruent square faces.

The area of a square = a² ( a is the length of the side )

Given

SA = 6a² ( divide both sides by 6 )

$\frac{SA}{6}$ = a² ( take the square root of both sides )

a = $\sqrt{\frac{SA}{6} }$ → B

Answer 2

Answer:

Rearranging will give you a.
