Question

I am not usre what the answer could be

Answer 1

`x \le 5`

Explanation:

Given

Shape: Cube

Dimensions: x, 3x and 2x

`Volume < 900`

Required

Show that
`x \le 5`

First, calculate the volume

`Volume = x * 3x * 2x`

`Volume = 6x^3`

`Volume < 900` becomes

`6x^3 < 900`

Divide both sides by 9

`x^3 < 150`

For
`x^3 < 150`, the value of x as to be: 1, 2, 3, 4 or 5

Hence:

`x \le 5`
