The height, width and thickness of a rectangular flower jar monument are 10m, 3M and 2m respectively, and the density is 2500kg / M & sup3; the ground can bear the maximum pressure of 150000pa. In order to make the ground can bear the monument, the monument is erected on the rectangular cornerstone with the height of 1m and the density of 2000kg / M & sup3 (1) What is the quality of the monument? (2) If the monument stands directly on the ground, what is its pressure on the ground? (3) what is the minimum bottom area of the cornerstone?
