A box in the shape of a cuboid has a height of x cm. The length is double the height. The width of the box is 2cm more than the height. The volume of the box is 400cm^3
Show that x^3+2x^2=200cm^3
ok for some reason I only manage to get down to x^3+2=200cm^3 or even x^3+4x^2=200cm^3 so someone please shed some light lmao im not thinking straight
Hence 2x^3+4x^2=400cm^3 - Here you want to divide EVERYTHING in the equation by two hence giving you the answer the question wants. Hope this helps! x^3+2x^2=200cm^3
