Question

A cuboid has a square base of side x cm. The volume of the cuboid is V cm^3 and the height is h cm.
a) Write down an expression for x in terms of V and h.
b) Find the value of x when V=150 and h=24
    I need help please!!!!!!!

Answer 1

You will need the formula for finding the volume of a rectangular prism (cuboid).
V = l x w x h

1. V = x^2 x h

2. To solve for x, you will substitute in the information you know.

150 = x^2 x 24
Divide both sides by 24 to get

6.25= x^2
The square root of 6.25 is 2.5.

x = 2.5 cm
