Question

Find the side of a cube whose surface area is $600c{m}^2$.

• A. $10cm$
• B. $20cm$
• C. $100cm$
• D. $10m$

Answer 1

The correct option is A $10cm$

Let $a$ be the side of the cube having surface area $600c{m}^2$.

$\therefore 6a^2=600\Rightarrow a^2=100\Rightarrow a=10$

Hence, the side of the cube $=10cm$.
