Question

Bonnie has a container in the shape of rectangular pyramid. The formula for the surface area of the enclosed space is S=lw+0.5Ph. Solve for P?

P= S - lw- 0.5h
P= S + lw + 0.5h
P= S-lw/ 0.5h
P= S/lw + 0.5h

Answer 1

S=lw+0.5Ph
isolate the term containing P
S - lw = .5Ph
divide by the factors muliplied by P , that is , the .5h

(S - lw)/(.5h) = P

The choice coming close is
P= S-lw/ 0.5h , if it had been typed correctly, should be

P= (S-lw)/(0.5h)
