Just multiply length x width x height.
Couple of problems there . . . 1). 'Feet' describe a length, whereas 'cubic feet' describe a volume. So they can't be converted. 2). A rectangle has no volume, since it's a plane (2-D) figure. Much like the question, a rectangle doesn't hold water.
2,272.6 cubic feet.
What's the depth? This is essential to find cubic feet. Depth x width x length = ? Cubic Feer
4 X 12 X 40 = 1920 cubic feet of water. 1 cubic foot of water = 7.48 gallons. 1920 cubic feet of water = 14,362.5 gallons
Not possible to say without any information about the depth.
A swimming pool that measures 12 feet by 30 feet and has an average depth of 6 feet contains approximately 16,157 gallons of water. 12 x 30 x 6 = 2160 cubic feet 1 cubic foot = approximately 7.48 gallons 2160 x 7.48 = 16156.8
Square feet is a measure of area. You do not get paint by the area - you get it in a volume - a litre, or quart or whatever. The container will give a meausre of the covergae which will depend on the surface being painted - its porosity, prior traetment, etc. Furthermore, a rectangle is an area. A rectangle can be measured in square feet but never in cubic feet. A rectangle measuring 40 cubic feet cannot exist!
the answer is in the question... 6X2X1.5=18.
You would measure the swimming pools length, width and depth to determine how many cubic feet of water is in the swimming pool. Length x Width x depth = cubic feet. Then measure the mass of 1 cubic foot of water by building a box 1'x1'x1'. Once you know the mass of 1 cubic foot of water - you'll know the mass of the water in the swimming pool.

2,134.88 cubic feet of water.
17 inches x 17.5 inches x 8.5 inches equates to a maximum water volume of about 10.95 US gallons or 1.464 cubic feet.
