How many tons of gravel are required for a 15' by 30' patio at a 6" finished depth?

To determine how many tons of gravel are required for a patio that measures 15 feet by 30 feet with a finished depth of 6 inches, you first need to calculate the volume of gravel needed in cubic feet, and then convert that volume to tons.

1. Calculate the area of the patio: The area is calculated by multiplying the length by the width.

• Area = 15 feet * 30 feet = 450 square feet.

2. Convert the depth from inches to feet: Since there are 12 inches in a foot, a depth of 6 inches is equivalent to 0.5 feet (6 inches ÷ 12 inches/foot = 0.5 feet).

3. Calculate the volume in cubic feet: Volume is calculated by multiplying the area by the depth.

• Volume = Area * Depth = 450 square feet * 0.5 feet = 225 cubic feet.

4. Convert cubic feet to tons: Gravel typically weighs about 1.5 tons per cubic yard, and there are 27 cubic feet in a cubic yard.

• First, convert the cubic feet to cubic yards: 225 cubic feet ÷ 27 cubic feet
