Question

A gift in the form of a cube, whose side measures 10 cm, has to be wrapped with gift paper, which costs ₹0.05 per cm². Find the cost of the gift wrap.

A.

₹60

B.

₹300

C.

₹600

D.

₹30

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.
