MCQ
The total surface area of a cube is 96cm2. Find its lateral surface area.
- A27cm2
- B512cm2
- C32cm2
- D64cm2
✓
Answer
- 64cm2
Solution:
Total surface area of cube = 6a2 (let a be a side of cube)
So, 6a2 = 96,
$\text{a}^2=\frac{96}{6}$
= 16
a = 4cm
Now, lateral surface area of cube is 4a2
So, 4a2 = 4 x (4)2
= 4 x 16
= 64cm2
