    Bonnie has a container in the shape of a 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 = The quantity S minus l times w all divided by 0.5 times h P = S divided by the quantity l times w plus 0.5 times h

    First take Iw to the left hand side.

    For the first step you remove Iw by the right hand side by subtracting Iw from both sides. \[S - Iw = Iw+0.5Ph-Iw\]

    So Iw on right hand side cancel out.

    Then you are left with, \[S-Iw=0.5Ph\]

    No. What we are trying to do is to get an equation for P. So P is left at right hand side.

    Finally you divide both sides by 0.5h. \[\frac{S-Iw}{0.5h}=\frac{0.5Ph}{0.5h}\] \[P=\frac{S-Iw}{0.5h}\]
