Students build a raft made of 15 logs lashed together. Each log is 53.2 cm in diameter and has a length of 6.17 m. Now they wonder how many students can be invited onto the raft before they start getting their feet wet. Find this number quickly before invitations get sent out. Assume the average student's mass is 67 kg and the density of wood is 600 kg/m3
