The formula for density is: D = m ÷ v

Where D = density, m = mass, and v = volume.

Since there are three variables and you know what two of them are, you can figure out what the third one is.

Plug in the numbers:

7.8 g/cm3 = m ÷ 800 cm3

7.8 × 800 = 6240 grams

ok so if every cm3 (a volume, a block with dimensions 1cmx1cmx1cm) has a mass of 7.8g, and we have 600cm3 then our mass must be

7.8 x 600 g



------------------------------------------------------

7.8 g per cm3--------- 7.8g/cm3

rho = density
m = mass
v = volume

m = v x rho

m = 7.8 g/cm3 x 600cm3
m = 7.8 x 600 g cm3/cm3 (multiplying and dividing by cm3 so they both cancel
m = 7.8 x 600 g

Asuming that those are square centimeters,it's down to basic math:

500g/10cm=50g/centimeter

That's 50 grams per square centimeter

How is the density of a steel ball different from a steel ship?

Density = mass/volume let us say the mass of the steel ball and the ship are same. but the steel ball is fully enclosed, a tight spherical volume, where as the ship is a hollow, occupies more volume (multiple times) as that of the spherical ball. Considering the first equation, u know well the density of steel ball is much higher than the steel ship.


A steel block has a volume of 008m and a density of 7840 kgm what is the force of gravity acting on the block in water?

9.81 m/s2 nine and eighty-one hundredths meters per second squared.


How do you deduct volume of steel in concrete?

If you know the dimensions of the slab, assuming that the slab is solid and in the shape of a rectangle, box, or square, you can calculate the volume with the formula: LxWxH which is length times width times height. This will give you the volume of the slab in cubic units (meters, feet, inches, whatever). Depending on the type of steel, you will have a different density ratio which can be used to calculate the weight of the slab. The density of low grade steel is something on the order of: 7850 kg/m3 so you would multiply your volume by the density ratio to get kilograms. If you know the weight of the slab and the type of steel, you can calculate the volume by dividing the weight by the density ratio. I hope this helps, perhaps you could provide more details on the type of steel and the exact property of the slab that you need (volume, weight, density.


What is the volume of a piece of metal?

The Volume of steel used should always be less than the volume of ship made out of it.The ratio could differ and hence there may be no specific ratio.The greater the (Ratio of Volume of ship:Ratio of Volume of steel used) say 3:1that means the ship can carry about 2 times the volume of the steel used.That means the water displaced would be 3 times volume of steel hence the water is applying the force on ship is 3 times weight of steel.***STUDY BUOYANCY


Will silver float in Mercury?

Steel don't float on water because the density of steel is greater than the density of water.

If the density of a solid is greater than that of water it sinks why then does a steel ship float in water when the density of steel is about eight times that of water?

The density of the entire ship is much less than the density of a ship-sized block of steel. That's accomplished by flattening the block of steel into a giant sheet, and then rounding the sheet on the bottom, so that it displaces much more water than the original solid block would. The final structure still has the same mass as the block of steel, but it has much more volume ... the volume of the steel, plus the additional volume of the cargo holds, the engine room, the galleys, the passenger cabins, the radio room, etc. So the original mass divided by the much greater volume winds up being a much smaller density than steel has. In fact, it winds up being smaller than the density of water.


What is more dense a steel boat or a block of steel?

A solid block of steel would be more dense than a boat made of steel. This is because even though the density of the material, steel, is constant, the form makes a difference to the overall density. The block of steel essentially contains nothing but steel, whereas the steel boat is "hollow" and contains air, as well as other construction materials such as wood.

What is density out of water carbon dioxide and steel which has greater density?

Steel has the greatest density of the three.


How ship floats on water surface?

The density of the VOLUME of the ship is less than the density of the water it displaces (pushes out of the way). While the steel of a steel hulled ship is denser than water, the steel plus the air enclosed by the steel is less dense.


How do you calculate unit weight of steel?

weight of all steel can be calculated by multiplying unit volume with density.


How do you weight calculate steel billets?

volume of the billet * density of d material i.e for steel density is aprox 7.8*10^-6 . volume * 7.8*10^-6.


Are bigger objects always heavier?

No. It isn't the size alone, but the density. A block of steel may be exactly the same size as a block of wood, but the steel is denser and therefore heavier.


How can a ship made out of steel with a density much higher than the density of water float on the water?

The steel has a density greater than water; but the ship does not. To calculate density, you divide mass by volume. This includes the mass - and the volume - of any air trapped inside the ship.


Which has higher density cold steel or hot steel?

When steel gets hot, it gets slightly larger due to thermal expansion. Since the mass stays the same, and density = mass/volume, it gets (very, very slightly) less dense. So cold steel is more dense than hot steel.


What is the density of steel as per IS 2062?

The density of steel as per IS 2062 will vary. This is because steel's density typically changes with composition.
