What is the density of a 64-g iron cube that displaces 8 mL of water?

Depends what metal.
If I might add to the above, you cannot calculate the density of a substance without knowing its mass (weight) and its volume, since density is mass per unit volume.
On the other hand, if you know the type of metal, and that it is pure, you can simply look up the density in a table since the density of all substances is constant for that substance, regardless of the weight or volume of the sample.

The displaced volume of water is the volume of the 64-gram iron cube. Milliliters and cubic centimeters are equal, so we can give the volume of the iron cube as 8mL = 8cm3.
Mass is given as 64g
Density = 64g/8cm3 = 8g/cm3
However this would not be pure iron, as pure iron has a density of ~7.87g/cm3.

Inwater a steel will float or sink?
It really depends on the shape. A cube of steel will sink but a boat displaces less water due to its shape and floats.
Which has the greatest density water granite iron or dry air?
its, IRON
Why an iron nail sinks in water whereas a cork for the same size floats?
Correct me if I'm wrong, but i believe that cork floats on water because its cells are empty.Any object dropped into a liquid displaces that liquid. A floating object weighs the same as the liquid it displaces. An object that sinks, weighs more than the liquid it displaces, so the stone is heavier than the cork causing it to sink. and not just that, cork is a lot less dense than a stone is.
Why iron nail sinks in water?
its density is greater than water, so it sinks.
Why will a block of iron float in mercury and sink in water?
The density of mercury is much greater than that of water, so the nail will not sink. The density of the nail is less than that of mercury and greater than that for water, so it sinks in the water.

If a sample of iron with a density of 7.874 gcm3 displaces 76.0 mL of water when placed in a beaker what is its mass?
The mass of iron is 598,4 g.
Why can an iron boat float but an iron cube can not?
The iron boat is an "empty shell" with air filled space inside, reducing its density compared to the iron cube which is iron all the way through.
What are the dimensions of a cube if the weight is 20grams?
That depends on the density of the material in the cube. It would be different if, say, the cube were made of ice, iron, or gold.

What is the density of ductile iron in gram per cm cube?
7.86 grams/cm3===========
Which has higher density iron or carbon or water?
Iron.
How are the density of wood and iron the same?
iron is more dense then water and wood is less dense then water. iron sinks because it is heavier then the density of water. wood sinks because woods density is lighter then the density of water.
What makes iron ships float?
The structure of an iron ship is such that its density is less than that of water. Anything with a density less than water will float in water.

What is the mass of 6.5 centimeters cube iron?
To determine the mass of Iron, its density is required. The formula used is Volume x Density = Mass. Assuming the Iron is pure and in solid state with a density of approximately 7.87g/cm3 at room temperature, its mass is around 51.2g.
Why should float on water while it is made up of iron sinks in water?
Anything which floats on water can only do so if it displaces, or moves out of the way, its own mass of water. Wood floats because it displaces a small amount of water, a large lump of iron is very heavy so it will keep displacing water until it has displaced its own mass.
