first u do 0.08m3 multiplied by 7840kg/m3 = 627.2kg then u multiply 627.2kg times 9.8m/s2 = 6,146.56 N <- force of gravity
then 0.08m3 times 1,000kg/m3 (density of water) = 80kg
80kg times 9.8m/s2 = 784 N <- buoyant force
6146.56 N subtract 784 N = 5,362.56 N <- net force
THE ANSWER IS 5,362.56! I just took the test!
Density = Mass/Volume is a measure of the amount of matter in a unit volume of a substance. Weight is the effect of gravity acting on a mass.
Weight would not exist w/o gravity. Weight is defined as mass times the force of gravity acting on that weight. Mass is constant, density is constant, and volume is constant, if gravity is the only variable.
Weight = (density) times (volume)The definition of density is mass/volume .Now [ weight = mass x gravity ], so [ mass = weight/gravity ], and [ density = weight/gravity x volume ] .So Weight = (density) x (volume) x (gravity)
Density is not affected by gravity. Density is affected by mass and volume, such that density = mass/volume. Weight, but not mass, is affected by gravity. Weight and mass are not the same thing.
The difference is that the mass density not effect by gravity but weight density effect by gravity. for example if mass density cotn in earth equal to 20 kg/m3 and weight density equal to 196.2 N/m3 this cotn will change the weight density in the moon but mass density not change because gravity moon diffrent to gravity earth mass density =mass/volume (no gravity) weight density= (mass * gravity)/volume (gravity)
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
weight = gravity times massand weight = density times volume
The weight of an object is determined by volume, density, and gravity.

Volume, density, and gravity.
Hmmm... technically false. Density is mass/volume - it is an intrinsic property. Weight is subjective to the force of gravity, while density is not.
Density is based off mass and volume, not weight and volume. Weight is a measurement of gravity, and changes based on strong the pull of gravity is in the area. Mass is a measurement of the amount of matter in an object, and does not change based on the pull of gravity. Density is Mass/Volume. Volume is a measure of how much space an object occupies. The more condensed matter is, the higher its density.
