How many gallons of water are in 12x12x12?

Answer 1

For the size in gallons for a rectangular aquarium, the formula is: (Length x Width x Height) divided by 231

So, 30 x 12 x 12 = 4320/231 = 18.7

I'd call it a 20 gallon tank, rounding up.

Answer 2

30 x 12 x 15 inches equals 5,400 cubic inches. This equates to 23.38 gallons.

Answer 3

If you mean inches, the tank will hold up to 29.6 gallons.

Answer 4

If you mean 12x12x12 feet, the total volume would be 12,926.34 US gallons of water.

Answer 5

That is approximately 32,313.6 US gallons.
