Question 74395
Volume=length*width*height
{{{Volume=(5x-2)(4x+3)(3x+2)}}}foil the 1st 2 factors
{{{Volume=(20x^2+15x-8x-6)(3x+2)}}}
{{{Volume=(20x^2+7x-6)(3x+2)}}}Now multiply the two remaining factors. You're going to multiply every term in the left parenthesis by 3x and every term in the left parenthesis by 2.
{{{Volume=60x^3+21x^2-18x+40x^2+14x-12}}}
{{{Volume=60x^3+61x^2-4x-12}}}So that's the volume of the box
