How many gallons is 7' x7'x3.5 '?

Answer 1

Assuming your pond is a perfect rectangular prism, with the measurements you indicated, its volume is 63 cubic feet. There are, approximately, 7.5 gallons in a cubic foot. So, the volume of your pool, in gallons is about 472. Again, that's assuming your pond is a perfect rectangular prism. Most ponds I've seen are not. First, the surface is not rectangular, but curved. Second, the bottom is not level, with the depth ranging from zero at the edges to a maximum depth somewhere in the middle. If the measurements you gave are just the maximum length, width, and depth, then the volume of your pond is quite a bit smaller. 464.94

(7x3x3x7.58) This is the formula that I was told to use

Answer 2

The volume of a rectangular prism is calculated by multiplying the three dimensions together. In this case, 7' x 7' x 3.5' equals 171.5 cubic feet. To convert this to gallons, you would then multiply this volume by 7.48 (the number of gallons in a cubic foot), giving you approximately 1282 gallons.

Answer 3

(30 x 20 x 5) = 3,000 cubic feet x 7.5 gallons/cubic foot = 22,441.6 gallons (rounded)

Answer 4

The answer will depend on the depth to which the surface needs to be covered.

Answer 5

7' x 7' x 3.5 ' is 1,282.9 gallons.
