Civil engineering formulas figure 12.212/29/2023 ![]() What is a yard of gravel?, A cubic yard of gravel look likes 3 feet long by 3 feet wide and by 3 feet height, which is equal as 27 cubic feet when multiply length by width by height= 3’×3’×3′ = 27 cubic feet.įor example:- if your driveway is 10 foot long by 10 foot wide by 2″ high, you do the following calculation:- 1) 2″ deep in feet = 2÷12 = 0.166 feet, 2) gravel quantity in cubic feet = 10’×10’×0.166′ = 16.6 cubic feet, 3) gravel quantity in yards = 16.6÷27 = 0.62 yards, and 3) gravel quantity in tons = 0.62×1.5 = 0.93 tons. Gravel is commonly sold by the cubic yard, so to find the material needed for a driveway, you need to find the volume in yards.
