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