What happens here
Determine the quantity of Class 5 base material needed. Using the dimensions of the area (210 lineal feet x 105 lineal feet) and a planned depth of 0.5 feet (6 inches), calculate the volume in cubic feet: 210 ft * 105 ft * 0.5 ft = 11,025 cubic feet. Convert cubic feet to cubic yards by dividing by 27: 11,025 cubic feet / 27 = 408.33 cubic yards. Finally, convert cubic yards to tons by multiplying by a factor of 1.36 (approximate conversion factor for aggregate): 408.33 cubic yards * 1.36 = 555.33 tons. Rounding up, this project requires 561 tons of recycled Class 5 base material. The proposal states this as 561 tons at a cost of $7,854 (which implies a price of $14 per ton including delivery and profit).
Goal: Determine the required volume and cost of Class 5 base material.
