anonymous · Answer

this is a rectangular paralellopipe
volume = area of base * height

soor hold have to change  the question

anonymous · Answer

by the floor, they mean the area of base
$$
x^3+6x^2-x-30=A(x)\times(x-2)\
A(x)=\frac{x^3+6x^2-x-30}{x-2}
$$
you can solve this by long-division or by synthetic division
