Question

Find the value of p in the right triangular prism if the surface area is 457.25 in2.

Answer 1

16.65 in
8.75 in
14.25 in ( I got this answer, but I wan to make sure)
9.45 in

Answer 2

Pick up the formula from the previous problem:

SA = p*h + 2*B where p is the perimeter of the base and h is the height and B is the area of the base.

457.25 = p * (9.9 + 6.2 + 11.7) + 2*(1/2)*9.9*6.2

This gives 14.23 approx but I guess that's close enough for government work. So, I agree with you. @dopegyal_
