Calculating Square Meters of Concrete

Concrete is a need for many projects throughout the home. If you’re going to make an entry or edge to a pool, one of the first things you should know is how much concrete will be needed to complete the work. To calculate the square footage of a concrete project, all you need to do is a few simple calculations.

How to

  1. Measure the length and width of the place where you’ll be placing the concrete.
  2. Multiply the length by the width to get the square footage. For example, if you plan to pour a concrete entrance that is 25 feet (7.6 m) long and 12 (3.7 m) wide, it will be 300 square feet (28 m 2).
  3. Measure all sides by an area that has no rectangle or square.
  4. Make a scale drawing of the area on graph paper.
  5. Divide the drawing into rectangles, squares and triangles.
  6. Look for an area for each section. For squares and rectangles, multiply the length by width. For triangles, multiply the base by the height and divide the product by two.
  7. Add the areas of ​​each section to get the total area.
  8. To determine the thickness of the concrete by dividing the inches by 12, For example, if you want your entry to be 4 inches (10 cm) thick, divide 4 by 12 for 0.333 feet (10 cm) of concrete.
  9. Multiply the area by the thickness. For this example, multiply 300 times 0.33 to obtain 99.99 cubic feet (2.83 cu m) of concrete.
  10. Change cubic meters to cubic yards because that’s how the concrete is usually measured. Do this by dividing 27 (3 feet by 3 feet by 3 feet). The equation looks like this: 99.9 / 27 = 3.7 cubic yards (2.82 cu m). You will need 3.7 cubic yards to pave an area 4 inches thick which is 25 meters long and 12 wide.
