Answer 3

I know that, I just needed to know if my answer was right

Answer 4

This is the situation. Area is the sum of all sides:

There are 2 walls that are 8 ft high and 12 ft wide: 2 * 8*12
Two walls that are 8 ft high and 15 ft long: 2 * 8 * 15
One ceiling that is 15 ft long and 12 ft wide: 15 * 12

So to get total area we sum all these to get
$$
\text{Area = }2\times8\times 12+2\times 8\times 15+15\times 12
$$
Is that what you did?
