## how many square feet are in a yard of concrete?

The amount of square feet you will fill with a yard of concrete will depend on the thickness.

FOR EXAMPLE: **How many bags of concrete do I need for a 10 x 10 slab?**

10 x 10 = 100 sq. ft.Â

For the calculations above, I rounded up to get an even number of bags.

## How Many Square Feet Are in a Yard of Concrete

A yard of concrete is a 3-dimensional measurement that is 3’x3’x3’. If you multiply 3 x 3 x 3 it equals 27. That means a yard of concrete contains 27 cubic feet (1’x1’x1’ or 12”x12”x12”) of concrete.

For our metric friends, a meter of concrete is different from a yard. A meter is 3.28 feet, so a cubic meter is 3.28’x3.28’x3.28’ or 35.29 cubic feet. That’s 8.29ft³ more concrete or almost a third of a yard larger!

## How Many 40 Pound Bags of Concrete in a Yard

A 40-pound bag of concrete mix makes 0.3ft³ of concrete which would cover 3.6ft² to a thickness of 1”. A yard of concrete is 27ft³, so 27 ÷ 0.3ft³ = 90 bags. A 40-pound bag of 4000psi concrete mix costs between $2.78 and $2.88 in my area. So, a yard of concrete mix will cost between $250.20 and $ 259.20 before taxes and weigh 3,600-pounds.
