Question

The mass of 30 cm cube of iron block is 240 gram find the density of the iron

Answer 1

Volume(V) of iron = (0.3m)^3=2.7*10^-3 m^3
Mass of iron(M) = 2.4*10^-3 Kg
Now ,
Density of iron = M/V
= 2.4*10^-3Kg/2.7*10^-3m^3
= 0.888 Kg/m^3

Answer 2

Answer:

$0.00888 g/cm^3$

Step-by-step explanation:

Side of cube = 30 cm

Volume of cube = $Side^3$

                           = $30^3$

                           = $27000 cm^3$

Mass of the cube is 240 grams

$Density = \frac{Mass}{Volume}$

$Density = \frac{240}{27000}$

$Density = 0.00888 g/cm^3$

Hence the density of the iron is $0.00888 g/cm^3$
