Calculate concrete volume of a square slab

Using measurements in feet:

Volume in Cubic Feet (ft3) = Width x Length x Depth

Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27

Calculate concrete volume of a round slab

Using measurements in feet:

Area of the Circle (ft2) = Pi x (Diameter/2)^2

Volume in Cubic Feet (ft3) = Depth x Area

Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27

Pi = 3.14

Number of Steps*

Calculate concrete volume of steps

Using measurements in feet:

Number of Steps is the total number of steps including the platform.

We calculate the volume in sections from the ground to the top of each section.

The platform and each step are each sections.

Volume in Cubic Feet Under Platform = Platform Depth x (Rise Height x Number of Steps) x Width

Counting steps starting at the bottom step and not including the platform we'll have Step Number 1, Step Number 2, Step Number 3, etc.

Volume in Cubic Feet Under Each Step = Run Depth x (Rise Height x Step Number) x Width

Total up the step volumes then the total concrete you need is

Volume in Cubic Feet = Volume in Cubic Feet Under Platform + Volume in Cubic Feet Under Steps

Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27

Calculate concrete volume of curbs & gutters

Using measurements in feet:

We calculate the volume in sections from the ground to the top of each section. The Curb and Gutter are each a section.

Volume in Cubic Feet Under Curb = Curb Depth x (Curb Height + Flag Thickness) x Length

Volume in Cubic Feet Under Gutter = Gutter Width x Flag Thickness x Length

Volume in Cubic Feet = Volume in Cubic Feet Under Curb + Volume in Cubic Feet Under Gutter

Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27
