Concrete is our business, and while we know everything there is to know about it, we want to make sure you have the answers to any questions you might have. That’s what this page is all about.

So, let’s start with the most basic of questions. Just what exactly is concrete? It is a composite material composed of fine and coarse aggregate bonded with a fluid cement that hardens over time. And did you know that concrete, a popular building material, is the second-most-used substance in the world after water?

This page should help you answer some of the most often-asked questions, such as:

- How many square feet are in a square yard of concrete?
- How many bags of concrete are in a yard?
- How many square feet are in a yard of concrete?
- What is a cubic yard of concrete?
- How many cubic feet are in a bag of concrete?
- How much concrete per fence post?
- How many yards does a concrete truck hold?

We’ll answer those questions and more. And remember, we are the premiere concrete contractors (Abingdon) around! We also have drainpipe supplies and septic tanks in Abingdon. **And if you’re looking for a calculation for a specific project, please feel free to contact us, so we can help make sure the numbers are correct**.

**How Many Square Feet are in a Yard of Concrete?**

The amount of square feet in a yard of concrete depends on how thick the piece of concrete is. For example, if the concrete slab is four inches thick, you’ll get about 81 square feet from 1 yard of concrete.

**How many Bags of Concrete Equals a Yard?**

The number of bags of concrete it takes to make a yard depends, of course, on the size of the bag. For example, if the bag is 80 pounds, it will take 45 bags of concrete to make a yard.

**How is a Yard of Concrete Measured?**

Concrete is measured in cubic yards, i.e., 1 cubic yard of concrete is 3 feet wide by 3 feet high by 3 feet deep. There are 27 cubic feet in 1 cubic yard. A cubic foot is 12 inches wide, 12 inches high, by 12 inches deep.

When determining yardage for your concrete driveway, patio, etc., the depth (or thickness) is used to figure the number. When ordering ready-mix concrete that comes from a concrete truck, it will be ordered by cubic yard. **Again, to make sure the calculations are correct, please contact Lakeside Ready Mix.**

**Frequently Asked Questions**

**How many cubic feet are in a yard of concrete?**

Concrete volume is measured in cubic yards. When poured on a perfectly level surface, one cubic yard will cover 27 square feet at one foot thick.

**How much does a yard of concrete weigh?**

A solid, unbroken slab of concrete weighs about 4,000 pounds per cubic yard.

**How many bags of concrete are in a yard?**

For one yard of concrete, you’ll need to use about 45 80-pound bags (or 90 40-pound bags). When you need a large amount, it is generally less expensive and takes less time to have ready-mix concrete delivered.

**How much is a yard of concrete in square feet?**

Concrete volume is measured in cubic yards. When poured on a perfectly level surface, one cubic yard should cover about 27 square feet at one foot thick.

**How much does a yard of concrete cover?**

Concrete volume is measured in cubic yards. When poured on a perfectly level surface, one cubic yard will generally cover 27 square feet at one foot thick. Thickness varies, however, so keep that in mind and contact Lakeside Ready Mix and let us make the calculations for you.

**How many yards are in a concrete truck?**

Concrete trucks weigh about 25,000 pounds and up to 40,000 pounds when carrying a full load. Their capacity is around 8 cubic yards but can be up to 10 cubic yards if fully loaded.

**How much concrete per fence post?**

This is subjective, but on average, it’ll take one to four bags of concrete per fence post. **Please contact Lakeside, and we can make the correct calculations for you.**
