Which expression represents the volume of the box? use the formula v=lwh 3x+1, 2x-1 * + 2

The expression of the volume of the box with dimensions of

(3x+1) by (2x-1) by (x+2) will be:

volume, V=lwh

plugging the values we get:

V = (3x+1) (2x-1) (x+2)

Expanding the above we get:

V = (3x+1) (2x^2+3x-2)

V=3x (2x^2+3x-2) + 1 (2x^2+3x-2)

V=6x^3+9x^2-6x+2x^2+3x-2

V=6x^3+11x^2-3x-2

Hence the expression for the volume will be:

V=6x^3+11x^2-3x-2
