Question

The volume of a sphere is $1.76{\text{cm}}^3$.

The volume of $25$ such spheres taking into account the significant figures is

• A. ${\text{0.44×10}}^2{\text{cm}}^3$
• B. ${\text{44.00 cm}}^3$
• C. $44.0{\text{cm}}^3$
• D. $44{\text{cm}}^3$

Answer 1

The correct option is D

$44{\text{cm}}^3$

Volume of $1$ sphere $=1.76{\text{cm}}^3$

Volume of $25$ spheres $=1.76\times 25=\frac{176\times 25}{100}=\frac{176\times \sout{25}}{\sout{100}}=\frac{\sout{176}\times 1}{\sout{4}}=44$

Hence volume of $25$ spheres is $44{\text{cm}}^3$
