Two boxes are pulled to right by a force of 43.0N. The left box has a mass of 71.0kg and the right box has a mass of 35.0kg. Calculate the acceleration of the system

Since we are told that the tank holds 1,000 cubic meters of oil, we know that we are dealing with volume (cuz volume is measured in cubic units, right?). So the formula for the volume for a cylinder is
 Our given bits of information are the radius and the volume itself, and we are solving for h, the height of the tank.  Fill in like this:

Doing all that math on the right gives you this: 1,000=9.42h and dividing both sides by 9.42 gives you that the height is 106.2 or, to the nearest meter, 106 meters.
