1.	The mass of an iron block is 158 g and density is 7.9 g/cm3 . Calculate the volume of the block.
Answer» Given: m = 158 g, d = 7.9 g/cm³ To find: v = ? Formula: density (d) = \(\cfrac{mass(m)}{volume(v)}\) Solution: From formula, v = \(\cfrac{m}{d}\) \(=\cfrac{158\,g}{7.9\,g/cm^3}=20\,cm^3\) \(\therefore\) The volume of iron block = 20 cm³

The mass of an iron block is 158 g and density is 7.9 g/cm3 . Calculate the volume of the block.

Answer»

Given: m = 158 g, d = 7.9 g/cm³

To find: v = ?

Formula: density (d) = \(\cfrac{mass(m)}{volume(v)}\)

Solution:

From formula,

v = \(\cfrac{m}{d}\)

\(=\cfrac{158\,g}{7.9\,g/cm^3}=20\,cm^3\)

\(\therefore\) The volume of iron block = 20 cm³
