Question

Please slice the problem so I can verify my work

Answer 1

The lateral surface area corresponds to the surface of the four rectangles that are not of 4x3 size. Then, the lateral area consists of two 6x3 and two 6x4 rectangles.

Thus,

`A_{\text{lateral}}=2(6\cdot3)+2(6\cdot4)=84`

Thus, the answer is 84in^2
