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!
Cubic yards.
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.
the answer is in the question... 6X2X1.5=18.

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.
