To find the surface area,here's the formula:
base area ×2 + side area ×4
thus, we have:
5×5×2 + 12×5×4
=50 + 240
=290
Thus the answer is 290 in^2
hope it helps!

10+7.5+12= 29.5 ft.
Second, you have to add the pieces that he has used
5.2 +6.2= 11.4 ft

29.5 - 11.4=18.1 ft.
I hope it helped. But, sorry don't know how to do number 2.
