Question

The volume of a rectangular prism is 840 in³. If the area of the base is 60 in², find its height. Draw and label a model to show your thinking.

Answer 1

Answer: 14 inches

Step-by-step explanation:

Given : The  volume of a rectangular prism : $V= 840\ in^3$

The area of base : $A=60\ in^2$

Let h be the height of the rectangular prism.

The formula to find the volume of a rectangular prism  is given by :-

$\text{Volume = Base Area}\times\text{Height}$

i.e. $840=60\times h$

i.e. $h=\dfrac{840}{60}=14\ in$   [Divide both sides by 60]

Hence, the volume rectangular prism = 14 inches
