Question

A lead block weighs 2,268 g and its volume is $200c{m}^3$, Then the density of lead is

• A. $11.34g/c{m}^3$
• B. $12.34g/c{m}^3$
• C. $11.55g/c{m}^3$
• D. $12.55g/c{m}^3$

Answer 1

The correct option is A

$11.34g/c{m}^3$

The unchanging relation between the weight of an object (w), its volume is (v) and density (d) of the material it is made of is given by $w=d\times v$

Given $w=2,268grams,v=200c{m}^3$. Then density of lead is,

$d=\frac{w}{v}=\frac{2,268}{200}=11.34g/c{m}^3$
