Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 15 cm
Given:
Total surface area of a closed cube is 1350 cm2
Formula used:
Total surface area of cube = 6 × side2 ----- (1)
Calculations:
Using equation (1), we get
⇒ 1350 = 6 × side2
⇒ side2 = 225
⇒ side = 15 cm
