The volume of the cuboid is: 10*5*2 = 100 cubic cm
Volume = 10 cm*10 cm*10 cm = 1000 cm3
The volume of a cube of iron that is 2.50 cm on each side is: 15.63 cm3
Well, darling, a 1-cm cube is a tiny little thing, measuring 1 centimeter on each side. If your mass is 0.10g less than the mass of a 1-cm cube of iron, then you're just a lightweight compared to that chunk of iron. But hey, at least you're still a cube!
2/7.85 = 254.777 millilitres
Iron is magnetic, lead is not.
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 Density of Iron is 7.874 g/cm^3. SO ...2000g/7.874g/cm^3 = 254 cm^3
The answer will depend on the size of the cube.
The small cube of iron will rust faster than the large flat sheet because it has a higher surface area-to-volume ratio, allowing more area for the oxidation process to occur. This increased surface area exposes more iron to the environment, leading to quicker rusting compared to the large flat sheet.
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.
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.
The volume of the cube is calculated by V = (2.00 cm)^3 = 8.00 cm^3. To convert cm^3 to m^3, divide by 1,000,000: 8.00 cm^3 / 1,000,000 = 8.00 x 10^-6 m^3. The density is mass divided by volume: 62.9 g / 8.00 x 10^-6 m^3 = 7862.5 kg/m^3.
