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 = 
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](https://tex.z-dn.net/?f=600in%5E2%5Btex%5D%3C%2Fp%3E%3Cp%3ENow%20put%20all%20the%20given%20values%20in%20the%20above%20formula%2C%20we%20get%3A%3C%2Fp%3E%3Cp%3EArea%20of%20cube%20%3D%20%5Btex%5D6a%5E2)


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