How much sand does it take to cover 15x24 3to 4 in deep?

The volume of sand that it would take to cover an area 15x24 feet wide and 3-4 inches deep is 2.92 or 3.9 cubic yards.

To calculate this volume, we need to first find the area in square feet:

15 feet * 24 feet = 360 square feet

Next, we need to convert the depth from inches to feet:

3 inches / 12 inches/foot = 0.25 feet

4 inches / 12 inches/foot = 0.33 feet

Using the average of the two depths, 0.29, we can then calculate the volume in cubic feet:

360 square feet * 0.25 feet = 90 cubic feet

360 square feet * 0.33 feet = 118.8 cubic feet

Therefore, the total volume of sand needed is approximately 90 to 119 cubic feet, which is equivalent to 2.92 cubic yards or 3.9 cubic yards.
