Question

The volume of a sphere is $1.76c{m}^3$. The volume of 25 such spheres taking into account the significant figure is:

• A. $0.44\times {10}^{2}c{m}^3$
• B. $44.00c{m}^3$
• C. $44.0c{m}^3$
• D. $44c{m}^3$

Answer 1

The correct option is C $44.0c{m}^3$

Volume of 1 sphere $=1.76c{m}^3$

Volume of 25 spheres $=1.76\times 25=44c{m}^3$

Since volume of a sphere is expressed in 3 significant figure, the answer should have 3 significant digits

=> Volume of 25 spheres $=44.0c{m}^3$
