Answer 1

Step-by-step explanation:

Bigger box:

2(lb +bh + lh)

2(20x15 + 15x5 + 20x5)

2(300+75+100)

950cm²

Smaller box:

2(lb +bh + lh)

2(16x12 + 12x5 + 16x5)

2(192+60+80)

2(332)

664cm²

Now add the extra 4% to both the boxes:

Bigger box:

4/100x950

38

950×38 = 988cm²

Smaller box:

4/100x664 = 26.56

664+26.56=690.56

Cost:

Bigger box :

988x200

197,600 boxes

197,600 x ₹10

₹1,976,000

Smaller box:

690.56x200

138,112 boxes

138,112x₹10
