This needs more information to supply a "best" answer. A 12ft by 12ft patio gives a surface area of 16 sq.yds. A yard of concrete is a cubic yard. The number of cubic yards depends on the thickness of the slab, and the size and depth of foundations (if any). This depends on the type of soil and subsoil, and whether you have very cold winters. If you live in a warm area, 3 yards is probably about right. If you are planning to do this yourself, try asking your local building inspector for his advice.

To calculate the cost of a 12ft by 12ft carpet, first determine the area: 12ft x 12ft = 144 square feet. If the cost is $99 per square foot, then the total cost would be 144 sq ft x $99/sq ft = $14,256. Therefore, a 12ft by 12ft carpet would cost $14,256.
(12ft x 12ft) square =144 sq ft. 12ft x (12 ft square) is 1728 cu ft.
13.378 square meters.

12ft x 12ft =144 ft2
12ft*25ft = 300 square feet
It is: 4 times 4 = 16 square yards
To determine how much gravel you need for a 12ft by 12ft garden, you first need to decide on the depth of the gravel layer. For example, if you want a depth of 3 inches (0.25 feet), you would calculate the volume as follows: 12ft x 12ft x 0.25ft = 36 cubic feet. Since there are 27 cubic feet in a cubic yard, you would need approximately 1.33 cubic yards of gravel.
