Question

A tool box has a volume of x3 + 8x2 + 11x – 20 cm3 and the height is x + 5 cm. Find the polynomial that would represent the area of the bottom of the tool box? Explain your reasoning.

Answer 1

\(v=x^3+8x^2+11x-20\)
\(h=x+5\)
volume = length x width x height
area = length x width
You are looking for the area, so substitute:
volume = area x height
and solve for area.
