Coverage Chart 2 Cubic Foot Bags

To calculate how many  2 cubic foot bags of material are needed, use the following procedure:

1 Determine the total square footage of the area needed to be covered. See the shape diagrams below to figure out the square footage of your area

2 Determine the desired depth of material. Determine the number of square feet covered by one bag at the desired depth using the table below.

3 Divide the total square footage of area being covered by the square foot coverage per cubic yard; based on desired depth in the table below. 

4 The number found tells you how many  2 cubic foot bags are needed for the area at that depth.

Depth

One 2 Cubic Foot Bag Covers
.5” 48 sq feet

1” 24 sq feet
2” 12 sq feet
3” 8 sq feet
4” 6 sq feet
5” 4.8 sq feet
6” 4 sq feet
7” 3.4 sq feet
8” 3 sq feet
9” 2.7 sq feet
10” 2.4 sq feet
11” 2.2 sq feet
12’’ 2 sq feet

Example: One 2 cubic foot bag spread at a depth of 3 inches covers 8 sq feet.

27 cubic feet = 1 cubic yard

13.5 two cubic foot bags = 1 cubic yard

(One 2 cubic foot bag covers 8 square feet 3” deep)

Triangle

The area, A, of a triangle can be found using the equation A = 1/2*B*H where B stands for the base of the triangle and H stands for the height. Any side can be chosen to be the base, but the height is the line that is perpendicular to the base and goes through the opposing vertex. After finding the area use the chart at the top of the screen to determine how much material  will be needed to achieve your desired depth.

Area = 1/2*(Base)*(Height)
Area = 1/2(B)(H)

Circle

The Area of a circle can be calculated by multiplying the radius (distance from the center to an edge of the circle) by its self and then by ? or 3.14. Then use the chart at the top of the screen to determine how much material  will be needed to achieve your desired depth.

Area = ?*(radius)2 or Area = ?*R*R

?= 3.14

Rectangle/Square

In a rectangle or square: (1) opposing sides of a rectangle are equal and parallel  (2) all of the angles are 90°. The area, A, of a rectangle can be found using the equation A = l*w. In this case, l stands for the length and w stands for the width. It does not matter which sides are labeled the length or the width.

Area = (length)*(width)

Trapezoid/Rhombus/Parallelogram

In a trapezoid, one set of opposing sides is parallel, but not necessarily equal.

The area, A, of a trapezoid can be found using the equation A = ½*(Base1 + Base2)*h. In this case, h stands for the line that is perpendicular to parallel sides B1 and B2.

Area = ½*(Base1+Base2)*h

Be sure to use the same units for all measurements.

You cannot multiply feet times inches, it doesn’t make a square measurement.

 

The area of a rectangle is the length on the side times the width.

If the width is 4 inches and the length is 6 feet, what is the area?

NOT CORRECT …. 4 times 6 = 24

CORRECT…. 4 inches is the same as 1/3 feet. Area is 1/3 feet times 6 feet = 2 square feet.
