A rectangular granite is 10 meters high, 3 meters wide and 2 meters thick, with a density of 2.5 x 10 cubic kilogram per cubic meter. The maximum bearing capacity on the ground is

According to the pressure formula P = f / s, the smaller the area, the greater the pressure. The mass of granite is 10 * 3 * 2 * 2.5 * 10 ^ 3 = 1.5 * 10 ^ 5kg, f = 1.5 * 10 ^ 6N
The area of huagangyan is S1 = 30m ^ 2, S2 = 20m ^ 2, S3 = 6m ^ 2, so S3 = 6m ^ 2 is the smallest
That is, the maximum pressure is p = f / S = (1.5 * 10 ^ 6) / 6 = 2.5 * 10 ^ 5pa

4. Is a giraffe the tallest animal on land, or an elephant?
5. Giraffe is the tallest animal on the earth at present, so its blood pressure is also the highest among the animals. The average height of an adult giraffe can reach 4.3m, its mass can reach 2T, and the landing area of one sole of a giraffe is 250cm2? (2) If the blood density of a giraffe is 1.05 × 103kg / m3, when its heart contracts, it is necessary to press the blood to the head 3M higher than the heart, then at least how much pressure should be produced when the giraffe's heart contracts? (systolic pressure refers to the pressure produced when the heart contracts. Atmospheric pressure is not taken into account in calculation. In this problem, G is taken as 10N / kg.)
