Landscaping & Concrete Material Estimation Guide
Ordering raw aggregate materials like crushed stone, pea gravel, or ready-mix concrete requires accurate volume conversions from linear dimensions to cubic yards and tonnage.
Converting Dimensions to Cubic Yards
Multiply Length (ft) x Width (ft) x Depth (ft) to find Cubic Feet, then divide by 27 to obtain Cubic Yards.
Cubic Yardage Formula
$$\text{Yards}^3 = \frac{L_{ft} \times W_{ft} \times (D_{in} / 12)}{27}$$
Standard formula for landscape material purchasing.
Numerical Example Calculation
A 25 ft x 12 ft patio filled 4 inches deep equals 100 cubic feet, which is approximately 3.70 cubic yards. At 1.4 tons/yd³, you need about 5.18 tons of gravel.
