Question

The total surface area of a cube is 294 in2. What is the length of each side of the cube?

Answer 1

let the side be s
thus 6s2=294
s2=49
s=7unit

Answer 2

Total surface area of cube
=294 ${cm}^{2}$
$6 {a}^{2} = 294 \\ {a}^{2} = \frac{294}{6 } \\ {a}^{2} = 49 \\ a = \sqrt{49} \\ a = 7cm \\ \\ \\ hope \: it \: help$
