The volume of a motorboat is 3.5 × 10 ^ 3 cubic meters, and the airship weighs 9 × 10 ^ 3 n. It can carry multiple objects at most? (air density = 1.29 kg / cubic meter) g=10N/Kg

The volume of a motorboat is 3.5 × 10 ^ 3 cubic meters, and the airship weighs 9 × 10 ^ 3 n. It can carry multiple objects at most? (air density = 1.29 kg / cubic meter) g=10N/Kg

The airship with gravity of 3 * 105 power is still in the air, and the volume air density is 1.3kg/m3, G is 10N

What metal density is 30571 times 10 cubic kg / m3

What metal density is 30571 times 10 cubic kg / m3
A: 30571 times 10 cubic kg = 30571000kg, a cubic meter of 30571 tons, the highest proportion of gold: 19.6 tons / m3, tungsten: 19.3 tons / m3, mercury: 13.534 tons / m3, silver: 10.5 tons / m3, wrong
