The formula for finding surface area is as follows:
SA=2(w*l + l*h + h*w)
First, lets start by plugging in the values
SA = 2 (24*27 + 27*38 + 38*24)
Now, because of the order of operations, we start inside the parentheses and multiply the values
In the end, our result is this:
SA = 2 (648 + 1026 + 912)
Now, we can add everything in the parentheses.
SA = 2 (2586)
Finally, distribute the 2 by multiplying the number in the parentheses by 2
SA = 5172
Therefore, the surface area is 5172 inches^2, or 5172 in^2
