Question

write a function to model the volume of a rectangular prism if the length is 10cm and the sum of the width and height is 18cm.

Answer 1

Let the length be l, width w and height h, then
Volume = length x width x height
l = 10cm, w + h = 18cm

V(h) = 10(18 - h)h = 180h - h^2
V(h) = 180h - h^2
