In order to measure volume, you require cubic feet. It helps in measuring that what amount of
water can be hold by a can. Cubic feet are mainly used for three dimensional objects. Can here
refer to refrigerators, swimming pools. It is necessary to find out volume of a particular object
because it helps you in making decision that you should be buying a particular object or not. In
markets, on basis of volumes, refrigerator is sold. Swimming pools are planted in gallons but
first you need to calculate its volume capacity in cubic feet and then it will be converted from
cubic feet to gallons.

In order to measure a can which will be equal to about four liters', use of gallons measurement is
done. A gallon is equal to about eight pints. In order to convert cubic feet to gallons you need to
follow certain steps:

1. Formula for cube is: CF=L*W*H.
In above stated formula, CF stands for cubic feet, L stands for length, W stands for width
and H stands for height. You need to memorize this formula.
2. Point stated above can be explained with help of an example. If you calculate CF of a
small pool whose length is 12 and width is 12 and height is 8 then CF can be calculated
as CF=12*12*8 which will be equal to 1152 cubic feet.
3. In order to find out cubic footage of a pool which is round in shape you need to area of a
circle. Area of circle = 22/7*R*R. Here R stands for radius.
4. Now if you want to convert cubic feet to gallons. According to its formula, about 7.48
gallons will be equal to 1 cubic foot.
5. In order to calculate, for pool stated in point 2, you need to multiply 1152 with 7.48 and
that will be equal to 8617 gallons. In a similar manner, you can also convert it for a pool
which is of round shape.

You need to remember certain points while converting: that in case of refrigerator, it's you
need to convert all inches measurement in cubic feet. Certain other products of your daily
life like room heaters and air conditioners should be purchased by keeping all these points in
your mind.
