Correct option is D
Given:
Side of the cube = 10 cm
Cost of gift paper = ₹0.05 per cm²
Formula Used:
Surface area of a cube = 6 × (side)²
Solution:
Surface area = 6 × (10)² = 6 × 100 = 600 cm²
Cost of gift wrap = Surface area × Cost per cm²
= 600 × ₹0.05 = ₹30
Thus, the cost of the gift wrap is ₹30.
