The volume of rectangular solid is x^3 +3x^2+2x-5) cubic cm and its height (x+1 )cm.what is the area of its base

Answer 1

divide
---- +x^2 +2x
x+1 | x^3 + 3x^2 + 2x - 5
----- x^3 + 1x^2
--------- + 2x^2 + 2x - 5
--------- + 2x^2 + 2x
remainder = -5

or
x^2 + 2x - 5/(x+1)

Answer 2

Since the volume is lwh, and we know h = x+1
then the base is lw
= (x^3 + 3x^2 + 2x - 5)/(x+1)
= (x^2 + 2x) - 5/(x+1)

I had expected the division to be exact.
Is there a typo?

Answer 3

The volume of a rectangular solid is (x^3 + 3x^2 + 2x) cubic cm, and its height is (x+1)cm. Whay is the area of the base?
