How to Calculate Building Materials Needed?

Using standard formulas, this calculator determines the quantities required. Here's a worked example:

Example:

Jackson wants to cover an area with concrete or gravel with the following dimensions:

Length = 58 ft
Width = 45 ft
Depth = 2 ft

Solution:

Step 1: Calculate Area and Volume

Area = Length × Width = 58 × 45 = 2610 ft²

Volume = Area × Depth = 2610 × 2 = 5220 ft³

Step 2: Calculate Weight (using density)

Weight = Density × Volume = 105 lb/ft³ × 5220 ft³ = 548,100 lb

Convert pounds to tons: 548,100 ÷ 2000 ≈ 274 tons

Step 3: Calculate Total Cost

Cost = Price per Ton × Weight = 46 × 274 = $12,604

Building Material Table:

Weight per cubic yard/meter for common construction materials:

Material	Weight per Cubic Yard (lbs)	Weight per Cubic Yard (tons)	Weight per Cubic Meter (kg)	Weight per Cubic Meter (metric tons)
Gravel (¼” – 2’)	2,800 – 3,400	1.4 – 1.7	1,660 – 2,020	1.66 – 2.02
Rock (2’ – 6’)	3,000 – 3,400	1.5 – 1.7	1,780 – 2,020	1.78 – 2.02
Sand (wet)	3,000 – 3,400	1.5 – 1.7	1,780 – 2,020	1.78 – 2.02
Sand (dry)	2,600 – 3,000	1.3 – 1.5	1,540 – 1,780	1.54 – 1.78
Topsoil (wet)	3,000 – 3,400	1.5 – 1.7	1,780 – 2,020	1.78 – 2.02
Topsoil (dry)	2,000 – 2,600	1 – 1.3	1,190 – 1,540	1.19 – 1.54
Riprap	3,400 – 4,000	1.7 – 2	2,020 – 2,370	2.02 – 2.37
