The Volume of Concrete in a Slab calculator computes the volume of concrete in a rectangle (square) slab. The value is function of the surface area (length * width), and the depth.
INSTRUCTIONS: Choose units and enter the following:
Volume of Concrete (V): The calculator returns:
However, these can be automatically changed to compatible units via the pull-down menu.
The Volume of Concrete in a Slab calculator compute the volume (3 dimensional space) of a concrete slab through the following equation:
V = L ⋅ W ⋅ D
The calculator converts the parameters into feet and computes the volume in cubic feet. It then uses the cubic feet to return volume in cubic yards for bulk concrete delivery, and divides it by the volume of the different sizes of concrete in bags. The most common are 40lb, 60lb and 80lb bags.
