There is a wooden sphere of radius 6√3cm. The surface area of the largest possible cube cut out from the sphere will be
-
- 864 cm²
- 464√3 cm²
- 462 cm²
- 646√3cm²
- 864 cm²
Correct Option: A
Diagonal of cube = Diameter of sphere = 6√3 × 2 = 12√3 cm.
∴ Edge of cube = | = 12 cm. | |
√3 |
∴ Surface area of cube = 6 × (edge)² = (6 × 12 × 12) sq. cm.
= 864 sq. cm.
