1 m^3 = 1000 lits and 1 lit = 1 kg (approx) therefore 1 m^3 = 1000 kg (approx) The above answer is ok for cold clean water approximatley but seawater has a slightly higher specific gravity than cold clean water approximatley 1.025 (temperature and actual TDS content dependant) therefore 1m^3 would weigh approximatley 1025kg.
1m3 of steel is the same as the first answer 7840Kg.
1m3 is equivalent to 1000 liters of water.
1800kg/m3
The weight of 1m3 of type 1 MOT stone is typically around 1,900-2,000 kg, depending on the specific density and characteristics of the stone.
500k g
120 kg/m3
1m3
The weight of 1 cubic meter (m^3) of cement is typically around 1440 kg.
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.
approx. 3,8 kg.
The weight of the sail boat is less than the weight of the water it displaces. That is its density is less than that of water.
