    Well, a r=10 and h=10 doesn’t mean much without units. 10 what? Feet? Meters? Inches? CM?

    Let’s take the OG numbers and assume feet, so 5,000 cubic feet. That’s not a useful volume measurement.

    1 cubic foot of water = 7.48052 gallons

    So 5,000 cubic feet of water = 37,402.6 gallons. That’s a viable volume measurement.

    1 cubic meter = 1,000 liters.

    5,000 cubic meters = 5,000,000 liters.

      The unit is unit.

      The math doesn’t care, and what you’re on about only really matters if the units don’t start as all the same or if you start converting between things.

      Its not supposed to mean anything, it’s about the equation not about the end result. We’re not calculating an actual cilinder
