How many square feet is a yard of concrete 3 inches thick?
One Cubic Yard = 27 Cubic Feet Length x Width = Square Feet
| 1 YD | 3 YD | |
|---|---|---|
| Depth | ||
| 3 Inches | 108 sq.ft. | 324 sq.ft. |
| 4 Inches | 81 sq.ft. | 243 sq.ft. |
| 5 Inches | 65 sq.ft. | 195 sq.ft. |
How do I calculate square feet into yards of concrete?
Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness.
Here’s what the math looks like for a 10′ by 10′ concrete patio:
- 10 x 10 = 100 square feet.
- 4 ÷ 12 =.33.
- 100 x.33 = 33 cubic feet.
- 33 x.037 = 1.22 cubic yards.

4 sq feet in that amount of cement.
How thick should my concrete slab be?
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
