That's the area of all six sides added together.

Calculate the area of each individual surface using the formula "length x width" and then add the six results to arrive at the final answer.

If you have the dimensions A, B and C, then the surface area is 2*(AB + BC + CA) square units
L*W*2 + L*H*2 + W*H*2= surface area

L= Length

W= Width

H= Height

*=Times
The surface area is the width times the length + the height times the length + the height times the width all multiplied by 2.
