Answer:
806 in^2
Step-by-step explanation:
we can start by breaking it up into two 11x13 sides and four 13x10 sides.
A=l*h
The first group of just two sides is 13*11 = 143, and for both sides 286 in^2
Then for the second group, 13*10 = 130, and for four sides, 520 in^2
We can add these values together for the total surface area, and we'll get 806 in^2 !
