To purchase a 4ft fish tank one can visit many stores or purchase them online. One can get them from The Home Depot, eBay, Walmart and All Pond Solutions.
To calculate the volume of water in a tank measuring 4ft x 4ft x 4ft, you would multiply the three dimensions together: 4ft x 4ft x 4ft = 64 cubic feet. Since 1 cubic foot is equal to approximately 7.48 gallons of water, the tank would hold around 478.72 gallons of water. This assumes the tank is filled to the brim without any obstructions or displacement.
In order to answer your question there is another dimension needed. width x length x depth = volume.
a tank top or skirt
That is 2.31 million cubic inches. The dimensions could change to whatever shape you needed, but an example would be somewhere around 20 feet wide x 8 feet high and 8 feet deep.
You cannot define a volume with only two linear dimensions.
2513.45 gallons.
A tank this size can hold a maximum of 3,590.65 US gallons of water.
38.4 inches
Depending of the type of tank. Tanks i this time period varied in height from 4ft to 10ft+.
3456 square inches.
It can be 3.5 ft deep, but you may prefer to give them more "land" space.
4ft*4ft*4ft=64 cubic feet
