Does the 300kpa mean that the 1595kg could sit on as little as 53sq/cm?
53 square cm = 0.0053 square m.
Multiply the mass in kg by 9.8 (say 10) to get the weight in Newtons. Say 16,000 N.
Pressure in Pascals = weight / area = 16,000 / 0.0053 = 3,000,000 Pa.
So no, that’s off by a factor of 10. It needs about 500 sq cm.
(But I think these numbers for 10% compression are really the destructive loads; I think these materials don’t compress at all and then crush irreversibly. If the specs quoted “recommended” loads or something, that would be more useful. But anyway, you’re certainly OK with 1600 kg over 4 square m.)
