Ans. :- 43.89 Kg is weight of 1 cubic feet 20 mm coarse aggregate. 1 CFT 10 mm aggregate weight in kg. The typical weight of 1 CFT (cubic foot) of 10 mm aggregate is approximately 46kg (100-pound). 1m3 or 35.32 CFT of 10 mm aggregate weighs about 1,620kg, so, weight of 1 CFT of 10 mm aggregate = 1,620/ 35.32 = 46kg.
