Question

I am not usre what the answer could be

Answer 1

Answer:

$x \le 5$

Step-by-step 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:

$x \le 5$
