Question

The volume of a rectangular solid is 2x³+7x²+2x-3.Its length and width are 2x-1 and x+3.Find its height.

Answer 1

Given that volume of a rectangular solid(cuboid) is

2x³+7x²+2x-3 and Its length and width are 2x-1 and x+3.

Now we have to calculate the height of the rectangular solid.

As we know that

volume of cuboid = L × B × H.

So,

(2x - 1) × (x + 3) × H =

2x³+7x²+2x-3

2x²+5x-3 × H = 2x³+7x²+2x-3

$H = \dfrac{2 {x}^{3} + 7 {x}^{2} + 2x - 3 }{2 {x}^{2} + 5 x - 3}$

Now,

We can calculate the value of height of the cuboid by solving about division as shown in attachment .
