Cubic footage (or volume) is simply the length x width x thickness. 4 inches x 1ft/12 inches = 0.333 ft Therefore, the driveways volume is: 30ft x 15ft x 0.333ft = 149.85 cubic feet, or better to just say 150 cubic feet.
Multiply length times width. IF your driveway was 1 foot thick that would be the number of cubic feet of concrete. HOWEVER- it is only 4 inches thick. That is .33 ft (one third of a foot). So take your answer you got from multiplying LxW, and divide by 3. That will be the number of cubic feet of the driveway's volume.
387 cubic feet. This is because 43x18x0.5 (as six inches is 1/2 of a foot) =387.
Convert everything to cubic feet. It should be easy then. Since one yard = 3 feet, 1 cubic yard = 27 cubic feet; also, one square foot x 1/4 foot = 1/4 cubic foot.
If you use a depth of 3 inches, that area will be about 16.2 cubic yards (around 20.785 tons) of gravel.

You say 12'x12 `—> that ' is the sign for feet. so if the patio is 12 feet by 12 feet then it is 144 square feet. You don't say what measurement the "4 thick" is, but I presume it is inches. 4 inches is 1/3 of a foot, so divide the square footage by 3 and that will give you the cubic footage - if the patio is 12 feet by 12 feet and 4 inches thick then the cubic footage is 48.
First, find the total square footage of your driveway. You can find this by multiplying the length of the driveway by the width of the driveway. When you have determined the square footage, you need to decide how thick you will apply the gravel. At a depth of 1", 1 cubic yard of gravel will cover 320 square feet. So for example, if you would like to put down 3 inches of material over 1000 square feet, you would do the following. 1000 square ft./320 = 3.125 3.125*3" depth = 9.375 yards
87.5 cubic feet
5,760 cubic feet.
There is no way to compare these two things. Square footage is a measure of area, while cubic feet is a measure of volume.
20*14*8 cubic feet = 2240 cubic feet.
387 cubic feet. This is because 43x18x0.5 (as six inches is 1/2 of a foot) =387.

1 Cubic Meter is 35.3147 Cubic Feet. Remember, a meter is about 36 inches.
147 cubic feet of cement are required.
