Question

Find the volume of the box with the edges x+2 2x+1 3x-1

Answer 1

V=edge*edge*edge
V=(x+2)+(2x+1)(3x-1)
V=(x*2x+x*1+2*2x+2*1)(3x-1)
V=(2x²+x+4x+2)(3x-1)
V=(2x²+5x+2)(3x-1)
V=2x²*3x-2x²*1+5x*3x-5x*1+2*3x-2*1
V=6x³-2x²+15x²-5x+6x-2
V=6x³+13x²+x-2. Hope it help!

Answer 2

(x+2)(2x+1)(3x-1)
(2x^2+4x+x+2) (3x-1)
(2x^2+5x+2)(3x-1)
6x^3+15x^2+6x-2x^2-5x-2
6x^3+13x^2+x-2
