Question

80 cm of iron weighs 624 g. Calculate the
density of iron. ​

Answer 1

$\large {\checkmark}$ Answer:

$\star$ Given:

→ Mass of iron = 624 g

→ Volume of iron = 80 cm³

→ Volume of the cube = (side)³

→ (80)³ = 80 * 80 * 80

→ 512000

$\star$ To Find:

→ Density of iron

$\star$ Solution:

⇒ Using the formula,

$\green{\boxed{\large{\boxed{\sf {Density = \dfrac{Mass}{Volume} }}}}}$

$\implies \sf {Density =\dfrac{ 624}{512000} }$

$\sf \implies Density = 0.00122\; g/cm^3$

$\sf \implies Density = 1.22\; kg/m^3$

Hence, the density of the iron cube is 1.22 kg/m³
