What is the weight of 1 cubic meter of water?
Do you mean mass or weight? To get the mass of 1 cubic meter of water: A cubic meter is a cube 1m x 1m x 1m Convert to centimeters this gives 100cm x 100 cm x 100cm Therefore the volumen of the cube in cubic cm is 1000000 cm3 1 litre = 1000 cm3 therfore : volume in litres is 1000000 / 1000 = 1000 l relative density of water is 1kg / l therefore the mass of the water is 1000kg or 1 tonne. Weight is the gravitational force exerceted on the water by the earths gravitational pull. I’m assuming the water is stationary at ground level and not in orbit or something daft. The effect of gravity at ground level is given by the constant g which is 9.8N/kg. Therefore the weight of the water is 1000 * 9.
