Quantity/Volume Calculators for Concrete
(Imperial)
These calculators are intended to allow you to calculate the imperial volume of concrete required for paths etc.
Three calculators are provided, the first for rectangle areas of concrete, the second for circular areas and the final one for triangular areas.

Rectangular volume calculator
For a simple rectangle, just use the length and width with the thickness in the calculator left. For irregular, basically square areas,

Circular volume calculator
For triangular shapes, work out the height and base of the triangle and use with the thickness in the calculator left. The 'height' is the distance between an angle and the opposite side where a line meets the side at right angles. The side it meets is the 'base'.

Triangular volume calculator
For triangular shapes, work out the height and base of the triangle and use with the thickness in the calculator left. The 'height' is the distance between an angle and the opposite side where a line meets the side at right angles. The side it meets is the 'base'.
