To calculate the number of 60lb bags in a cubic yard, we need to first convert the cubic yard measurement to cubic feet. As mentioned earlier, 1 cubic yard is equivalent to 27 cubic feet. Therefore, to convert cubic yards to cubic feet, we simply multiply the cubic yards by 27.

1 cubic yard = 1 x 27 = 27 cubic feet

Now, let’s calculate the volume of each ingredient in the concrete mix (1:2:3) for our 27 cubic feet of concrete.

1 part cement = 1/6 x 27 = 4.5 cubic feet

2 parts sand = 2/6 x 27 = 9 cubic feet

3 parts gravel = 3/6 x 27 = 13.5 cubic feet

To convert these volumes to pounds, we need to multiply each by the density of concrete, which is roughly 150 pounds per cubic foot.

1 part cement = 4.5 x 150 = 675 pounds

2 parts sand = 9 x 150 = 1350 pounds

3 parts gravel = 13.5 x 150 = 2025 pounds

To determine the number of 60lb bags in each ingredient, we divide the total weight by 60.

1 part cement = 675/60 = 11.25 bags

2 parts sand = 1350/60 = 22.5 bags

3 parts gravel = 2025/60 = 33.75 bags

Therefore, to create 27 cubic feet of concrete, you will need a total of 67.5 60lb bags (11.25 bags of cement + 22.5 bags of sand + 33.75 bags of gravel).

In conclusion, there are approximately 67.5 60lb bags of concrete in a cubic yard for a standard concrete mix of 1:2:3.
