How many square feet will a yard of decomposed granite cover at 3 inches thick?

Answer 1

Assuming that you mean a cubic yard of decomposed granite, I'll try to answer this question.

Information needed to answer question:

1. A yard is twelve (12) inches multiplied by three (3), that is to say, three (3) feet, or thirty-six (36) inches.
2. A square yard is one-thousand-two-hundred-ninety-six (1,296) square inches.
3. There are nine (9) square feet in a square yard.
4. Cube is calculated by multiplying the height by the width, and then multiplying that by the length.
5. Thirty-six (36) multiplied by thirty-six (36) equals (=) one-thousand-two-hundred-ninety-six (1,296).
6. Twelve (12) multiplied by nine (9) equals one-hundred-eight (108).
7. One-thousand-two-hundred-ninety-six (1,296) multiplied by thirty-six (36) equals (=) forty-six-thousand-six-hundred-fifty-six (46,656).
8. Fifteen-thousand-five-hundred-fifty-two (15,552) divided by one-thousand-two-hundred-ninety-six (1,296) equals (=) twelve (12).
9. Forty-six-thousand-six-hundred-fifty-six (46,656) divided by three (3) equals (=)fifteen-thousand-five-hundred-fifty-two (15,552).

Taking this information:

We need to find out how many cubic inches there are in a cubic yard. So, sincecube is calculated by multiplying the height by the width, and then multiplying that by the length, and a yard is twelve (12) inches multiplied by three (3), that is to say, three (3) feet, or thirty-six (36) inches, then we can calculate that thirty-six (36) multiplied by thirty-six (36) equals (=) one-thousand-two-hundred-ninety-six (1,296). But that is only the square inches in a square yard. We want the cubic inches in a cubic yard. So, multiply one-thousand-two-hundred-ninety-six (1,296) by thirty-six (36) and we get forty-six-thousand-six-hundred-fifty-six (46,656). So that is how many cubic inches there are in a cubic yard. Now, since the layer of granite is going to be three (3) inches thick, we need to divide forty-six-thousand-six-hundred-fifty-six (46,656) by three (3). Forty-six-thousand-six-hundred-fifty-six (46,656) divided by three (3) equals (=) fifteen-thousand-five-hundred-fifty-two (15,552). Now we need to divide fifteen-thousand-five-hundred-fifty-two (15,552) by one-thousand-two-hundred-ninety-six (1,296) to find out how many square yards the three-(3)-inch layer will cover. Fifteen-thousand-five-hundred-fifty-two (15,552) divided by one-thousand-two-hundred-ninety-six (1,296) equals (=) twelve (12). That is how many square yards the granite will cover. We need to find out how many square feet the granite will cover, so, since there are nine (9) square feet in a square yard, we will multiply twelve (12) by nine (9). Twelve (12) multiplied by nine (9) equals one-hundred-eight (108). So there the answer is.

One cubic yard of decomposed granite will cover one-hundred-eight (108) square feet in a three-(3)-inch layer.

But we need to double-check our work. So taking the number one-hundred-eight (108), we will divide it by four to find out how many cubic feet of granite there are, and we reach the number twenty-seven (27). That is the amount of cubic feet of granite. There are twelve (12) inches in a foot. There are one-hundred-forty-four (144) square inches in a square foot [twelve (12) multiplied by twelve (12)]. One-hundred-forty-four (144) multiplied by twelve (12) equals (=) one-thousand-seven-hundred-twenty-eight (1,728). That means there are one-thousand-seven-hundred-twenty-eight (1,728) cubic inches in a cubic foot. One-thousand-seven-hundred-twenty-eight (1,728) multiplied by twenty-seven (27) equals (=) forty-six-thousand-six-hundred-fifty-six (46,656)! Since the equations work out, this answer is correct!

So here's the answer one more time:

One cubic yard of decomposed granite will cover one-hundred-eight (108) square feet in a three-(3)-inch layer.
