To start, the formula of the surface area of a rectangular prism is A=2LW+2LH+2HW and to find the surface area, you must plug the values into the formula in order to find the surface area of the prism. Since your height is 6, your width 7, and your length is 11, plug the values into the formula. This would look like this:
A=2(11)(7)+2(11)(6)+2(6)(7)
When simplified, you should get A= 154+132+84
Then, you add and you get your answer as 370 meters squared.
