How much gravel to fill an area 10 by 5?
To determine how much gravel is needed to fill an area of 10 by 5 feet, you first calculate the area by multiplying the length and width: 10 feet × 5 feet = 50 square feet. Next, decide on the desired depth of the gravel fill (for example, 3 inches or 0.25 feet). Multiply the area by the depth to find the volume in cubic feet: 50 square feet × 0.25 feet = 12.5 cubic feet of gravel required.
