Question from dale: how many gallons in an oval shaped tank, 72in long x46.5in wide x23in deep |
Dale,
If your oval is an ellipsoid then the volume is 
. Since your dimensions are in inches this expression will give you the volume in cubic inches. There are 231 cubic inches in a US gallon and 277.42 cubic inches in an Imperial gallon so divide the number of cubic inches by either 231 or 277.42 to obtain the number of gallons.
