From this sentence, we can create a direct variation formula:
The volume, V, of a tank varies directly with its height, h

step 1 - put in the numbers you are given to find k. the numbers were
h = 12, V = 300. SO, we get

solving for k, we get
K = 75.
step 2 - rewrite the equation with your new k value as

we are done.

The volume, V, of a tank varies directly with its height, h. A tank 12 feet high holds 300 cubic feet. Write an equation relating v and h.
------------------------------
V = kh

Find "k" based on the information given.
---
300 = k*12
k = 300/12
k = 25
----------
Equation:
V = 25h
