MCQ
The volume of a cube is $2744 \ cm^3$. It surface area is
- A$196 \ cm^2$
- ✓$1176 \ cm^2$
- C$784 \ cm^2$
- D$588 \ cm^2$
✓
Answer
Correct option: B.
$1176 \ cm^2$
$\because \text { volume of a cube }=(\text { side })^3$
$\Rightarrow a^3=2744$
$\Rightarrow a=\sqrt[3]{2744}=14 \ cm$
$\therefore$ Surface area $=6 a ^2=6 \times 14 \times 14=1176 \ cm^2$
$\Rightarrow a^3=2744$
$\Rightarrow a=\sqrt[3]{2744}=14 \ cm$
$\therefore$ Surface area $=6 a ^2=6 \times 14 \times 14=1176 \ cm^2$
