Question

the mass of an iron cube of volume 10 cm to the power 3 is found to be 78 g what is the density of the iron cube​

Answer 1

$\huge{\mathcal{\underline{\pink{Solution:-}}}}$

Mass of iron cube = 78g

Volume of iron cube = 10 cm³

$\large\rm\bold{\boxed{Density\:=\:\frac{Mass}{Volume}}}$

$\large\rm{\implies{Density\:=\:\frac{78}{10}}}$

$\large\rm{\implies{Density\:=\:7.8\:g/cm^3}}$

∴ Density of iron cube = 7.8 g/cm³

Answer 2

Answer:

\huge{\mathcal{\underline{\pink{Solution:-}}}}

Solution:−

Mass of iron cube = 78g

Volume of iron cube = 10 cm³

\large\rm\bold{\boxed{Density\:=\:\frac{Mass}{Volume}}}

Density=

Volume

Mass

\large\rm{\implies{Density\:=\:\frac{78}{10}}}⟹Density=

10

78

\large\rm{\implies{Density\:=\:7.8\:g/cm^3}}⟹Density=7.8g/cm

3

∴ Density of iron cube = 7.8 g/cm³
