When Ordering Concrete

This concrete calculator will help you in estimating the amount of concrete needed for your project. The amount given as needed does not include any waste. Depending on your job, we recommend adding anywhere from an extra 4% to 10% to your concrete required calculation to make sure you have enough concrete to finish the job. Ask when ordering the concrete. They will be able to give you a good idea of what is needed.
Formula
Area = 𝛑MN
Perimeter = 2𝛑√(M²+N²)/2
where 𝛑 equals 3.14159
M is length A ÷ 2
N is length B ÷ 2

To convert cubic metres to cubic feet, multiply cubic metres * 35.3146667214886 
To convert cubic metres to cubic yards, multiply cubic metres * 1.30795061931439
Example Calculation
Length A = 40 metres
Length B = 6 metres
Depth = 152 millimetres
Area
M = 40 ÷ 2     M = 20 
N =  6 ÷ 2      N = 3

3.14159 * 20 * 3 = 188.495559  rounded to 188.5
The surface area of this slab is 188.5 square metres.
Perimeter
2 * 3.14159 * √(20² + 3²) ÷ 2 
2 * 3.14159 * 14.3  =  89.84954989 rounded to 89.9
The perimeter (circumference) of the slab is 89.9 lineal metres.
Volume
Multiply the area square footage by the depth of the slab.
First, convert the 152 millimetres to metres by dividing by 1000.
152 ÷ 1000 = 0.152
152 millimetres  = 0.152  metres
188.5 * 0.152 = 28.652
You will need 28.652 cubic feet of concrete for this slab.
The difference with the calculator result for these measurements is due to rounding.
