3 (125)
বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Solution:
Given that,
Total surface area of a cube, S = 150 square units.
We know,
Surface area of a cube, S = 6a2
⇒ 6a2 = 150
⇒ a2 = 150/6
⇒ a2 = 25
⇒ a2 = 52
∴ a = 5
And we know, Volume of a cube, V = a3
= 53
= 125
So the volume of the cube is 125 cubic units.
