The difference between the surface areas is 198 square inches

How to determine the difference between the surface areas?

The side lengths are given as:

L = 7 inches

l = 4 inches

The difference between the surface areas is calculated as:

Difference = 6(L^2 - l^2)

Substitute the known values in the above equation

Difference = 6(7^2 - 4^2)

Evaluate

Difference = 198

Hence, the difference between the surface areas is 198 square inches
