The formula for volume of a rectangular prism is `V= l times w times h`

As we have the volume already, we will manipulate the formula to find the height:

`V/(l times w) = h`

Now substitute the values we have been given:

`therefore 36000/(30 times 20) = h`

`therefore 36000/600 =h`

`therefore h=60cm`

**Ans: The height of the tank is 60cm**
