The Volume of a Concrete Footer calculator computes the volume of concrete in a footer. 

INSTRUCTIONS: Choose units and enter the following:

• (L) Length of Footer 
• (W) Width of Footer
• (D) Depth of Footer

Concrete volume in footer (V): The calculator returns the volume of concrete in cubic yards.  However this can be automatically converted to compatible units via the pull-down menu.  The calculator also returns the equivalent volume in number of bags of concrete in different bag sizes:  

• 40lb bags
• 60lb bags
• 80lb bags

The Math / Science

The volume of concrete in a footer is computed as follows:

V = L * W * D

where:

• V = Volume of Concrete in a Footer
• L = Length of Footer Channel
• W = Width of Footer Channel
• D = Depth of Footer Channel

Foundations - Footers - Piers 

• Blocks in a Foundation: Computes the number of blocks needed for a foundation based on the dimensions of the foundation and the size of the blocks with a standard size mortar joint.
• Concrete in a Poured Foundation: Computes the volume of concrete, the square feet of the forms and the number of 4'x8's needed for the forms.
• Concrete in a Wall: Computes the volume of concrete in a wall based on the dimensions.
• Concrete in a Footer: Computes the volume of concrete for a footer based on the length, width and depth of the footer.
• Concrete in a Footer (Cross Section): Computes the volume of concrete for a footer based on the length and cross-section area of a footer
• Concrete in a Pier: Computes the volume of concrete in a circular pier based on the radius and depth of the pier.
• Piers for a Building: Computes the number of piers and volume of concrete need for the piers of a building (e.g., pole barn) base on the building dimensions, pier spacing, diameter and depth.
• Concrete around Circular Post: Computes the volume of concrete around a number of round posts in a round hole based on the size of the hole and dimensions of the post. 
• Concrete around Square Post: Computes the volume of concrete around a number of square post (e.g., 6x6) in round hole based on the dimensions of the post, depth and width of the round hole.
• Water Needed for Concrete: Computes the water volume needed to mix concrete.
• Price of Bulk Concrete: Computes the price of bulk concrete including delivery based on mileage and on-site pumping cost.
