The equation that can be used to find the length of the tank is 240 = l × 12 × 10
<h3>How to find the volume of rectangular prism?</h3>
The volume of a rectangular prism can be found as follows:
volume of rectangular prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
volume of rectangular prism = lwh
volume of rectangular prism = 240 ft³
h = 12 ft
w = 10 ft
Therefore, the let's find the length of the tank.
240 = l × 12 × 10
240 = 120l
divide both sides by 120
l = 240 / 120
l = 2
