According to a "pool calculator" that I found on the net.... approximately 224.1 gallons.
1,915 gallons for a tank that size.
A rough (high) estimate will use the volume of a rectangle. 155.42 US gallons
74.42 gallons.
Cannot be answered without knowing the length/height of the tank.
Approx 2.1 Imperial gallons = 2.5 US gallons.
The height of 400 gallons of water would depend on the shape of the container. 400 US gallons has a volume of about 206,000 cubic inches, so if the inside of the container was about 59 inches square, it would also be about 59 inches high.
50,000 gallons
This size tub holds 249 US gallons of water.
367.012987 gallons
168.311 US gallons.
Any container 30 inches long 13 inches wide and 13 inches high has a volume of 22 gallons
Need the length of the tank also to determine the amount of oil
= 93.09 gallons (US) = 77.51 gallons (imperial)
