Question

The base of a rectangular prism is 20 cm 2 . If the volume of the prism is 100 cm 3 , what is its height?

5 cm
10 cm
80 cm
120 cm

Answer 1

5 CM

Explanation:

Answer 2

The correct answer is 5 cm. We can find this by substituting the values we've been given into the formula for the volume of a rectangular prism.

V = lwh Volume of a rectangular prism
100 = 20h Substitute. Keep in mind that the base is length times width, so 20 accounts for both variables.
5 = h Divide both sides by 20

The height of the rectangular prism is 5 cm.

Hope this helps!
