Question 230694
The surface area S of a right prism is given by 
S=2B+Ph, 
where B is the area of the base, P is the perimeter of the base, and h is the height of the prism. 
Solve for h. 
------------------
S = 2B + Ph
Subtract 2B from both sides:
Ph = S-2B
Divide both sides by P:
------------------
h = (S-2B)/P
