the depth is x+2

Find linear expressions with integer coefficients for the other dimensions and next if the depth of the chest is 9feet deep what are the other dimensions?

**Damon**, Sunday, February 14, 2010 at 6:41pmV = depth * width * length

V = (x+2) * w * l = x^3 - 5x^2 -8x +12

so divide x^3 - 5x^2 -8x +12 by (x+2)

and get

l * b = x^2 -7x +6

which is

(x-6)(x-1)

so

length = x-1

width = x-6

depth = x+2

take it from there
