Some places sell crushed stone by the ton, while others sell it by the cubic yard (yd3) (a lot of times just called a yard).Here are the amounts in cubic yards and tons using the dimensions you posted (40ft long x 8ft wide x 4in deep)? yd3 = 40ft x 8ft x 4in x (1ft/12in) x (1yd3/27ft3) = 3.95yd3 => 4 cubic yardsFrom the table, we find crushed stone is 100 lb/ft3 and crushed granite is 103 lb/ft3so,crushed stone:tons per yd3 = 100 lb/ft3 x (27ft3/1yd3) x (1 ton / 2000 lb) = 1.35 tons (English) of crushed stone in one cubic yardcrushed granite:tons per yd3 103 lb/ft3 x (27ft3/1yd3) x (1 ton / 2000 lb) = 1.3905 tons (English) of crushed stone in one cubic yardThe difference in weight is negligible between the two materials, so using either one, you would need roughly 5.5 tons (English) of crushed stone.
