The relative density (Rd) steel is 7.8 find the mass of a solid steel cube of solid 10 cm,

Answer 1

To find the mass of a solid steel cube, we can use the formula:

Mass = Volume x Density

First, we need to find the volume of the cube. The volume of a cube is calculated using the formula:

Volume = Side length^3

Given that the side length of the cube is 10 cm, the volume of the cube is:

Volume = 10 cm x 10 cm x 10 cm = 1000 cm^3

Next, we can calculate the mass of the cube using the formula:

Mass = Volume x Density

Given that the relative density of steel is 7.8, we can convert it to the density of steel in g/cm^3 by multiplying it by the density of water (1 g/cm^3):

Density of steel = 7.8 x 1 g/cm^3 = 7.8 g/cm^3

Plugging in the values for volume and density, we get:

Mass = 1000 cm^3 x 7.8 g/cm^3 = 7800 g

Therefore, the mass of the solid steel cube with a side length of 10 cm is 7800 grams.
