Question

Answer this with proper explanation.

Answer 1

ANSWER :

• DIMENSION OF BIGGER BOX :

Dimension of bigger box = 30 cm × 20 cm × 5 cm

Total surface area of bigger box = 2(lb + bh + lh)

= 2(30×20 + 20×5 + 30×5)

= 2(600+100+150)

= 2(850)

= 1700 cm²

• DIMENSION OF SMALLER BOX :

Dimension of smaller box = 15 cm × 12 cm × 5 cm

Total surface area of smaller box = 2(lb + bh + lh)

= 2(15×12 + 12×5 + 15×5)

= 630cm2

Total surface area of 250 boxes of each type = 250(1700 + 630)

=250×2330 cm2 = 582500 cm2

• EXTRA AREA REQUIRED :

Extra area required = 5/100(1700 + 630) × 250 cm2 = 29125cm2

• TOTAL CARDBOARD REQUIRED :

Total Cardboard required = 520000 + 29125 cm2 = 549125 cm2

• TOTAL COST OF CARDBOARD SHEET :

Total cost of cardboard sheet = ₹(549125 × 4)/1000 = ₹ 2196500/1000 = ₹ 2196.5
