Answer 1

hey..

die is in the shape of cube..

total surface area of cube = 6s
= 6(14)
= 84mm^2

cost of paper = 84 X 2
= 168 rupees

Answer 2

Dear Student,

● Answer -

Cost = 2352 ₹

◆ Explanation -

# Given -

s = 14 mm

rate = 2 ₹/mm^2

# Solution -

Total surface area of the die -

TSA = 6s^2

TSA = 6 × 14^2

TSA = 6 × 196

TSA = 1176 mm^2

Total cost of the paper is -

Cost = TSA × rate

Cost = 1176 × 2

Cost = 2352 ₹

Hence, the cost of covering the die is 2352 ₹.

Thanks dear. Hope this helps you...
