Exercise (5.1) A civil engineer involved in construction requires 4800, 5810, and 5690 m³ of sand, fine gravel, and coarse gravel, respectively, for a building project. These materials can be obtained from three pits. The composition of these pits is: Fine Coarse Sand Gravel Gravel % % Pit 1 52 30 18 Pit 2 20 50 30 Pit 3 25 20 55 by Gauss elimination How many cubic meters must be taken from each pit in order to meet the engineer's needs?
