Answer 1

Bigger Box
TSA= 2(lb+bh+lh)
       = 2(500+100+125)
       = 1450cm²
TSA of all Boxes = 1450 x 250 = 362500cm²
TSA of all Boxes including flaps = 362500 + (5% x 362500) = 380625cm²

Smaller Box
TSA= 2(lb+bh+lh)
       = 2(180+60+75)
       = 630cm²
TSA of all Boxes = 630 x 250 = 157500cm²
TSA of all Boxes including flaps = 157500 + (5% x 157500) = 165375cm²

Amount of Cardboard required = 546000cm²
Total price= Rs. (546000/1000) x 4 = Rs. 2184
