Answer : The length of an edge of cube is, 10 inches.

Step-by-step explanation :

The formula used for area of cube is:

Area of cube = $6a^2$

where,

a = edge

We are given that:

Area of cube = $600in^2[tex]Now put all the given values in the above formula, we get:Area of cube = [tex]6a^2$

$600in^2=6a^2$

$a=10inches$

Therefore, the length of an edge of cube is, 10 inches.
