Question

The height of a box is one more than its length l, and the length is one more that its width w. Find a polynomial for the volume V in terms of the following: the width w, the length l, and the height h.

Answer 1

What is the formula for volume?

Answer 2

V= l*w*h

Answer 3

Ive got h= L + 1, L= w + 1, W = L -1

Answer 4

OK.
If h = l+1, and w=l-1, what would L*w*h equal?

Answer 5

L*(L+1)*(L-1) = ?

Answer 6

oh wow, so (L^2 +L) (L-1) = L^3-L^2 + L^2 -L = L^3-L

Answer 7

so this is in terms of L right?
