What Is The Best Way To Calculate

Believe it or not, all of those times your teacher told you that you needed some math skills and you ignored the idea was real. Here is one of those times where having some quality math skills comes into play. Let’s review the best way to get your measurements:

  • Measure the area based on the length of the area in inches.
  • Use your measuring tape and record the width of the area needing coverage in inches
  • Take your measurements and divide by 12 in order to determine the feet. For example, if the length is 60 inches, it would be 5 feet. If the width were 50 inches, you would need 4.1667 feet covered.
  • Now, look at the depth by dividing the inches needed in depth by 12. This allows you to convert it to feet. For example, 2 inches in depth, divided by 12, is 0.1667 feet needed.
  • Next, multiply your length times your width to determine the depth needed. This will allow you to calculate the cubic feet of rock needed for the area. For example, a 5 by 4.1667 feet area at a depth of 0.1667 feet, would give you 3.4729 in cubic feet.
  • Lastly, divide the cubic feet by 27 to determine your cubic yards. Since there are 27 cubic feet in one cubic yard, you will find that 3.4729 divided by 27 equals 0.1286 cubic yards.

How Much Does It Cost
