answer urgent.............###??????????

Answer 1

Area of first type of a box = 2(60x40  +  60x25  +  40x25)

= 2(2400 + 1500 + 1000) = 2 x 4900 = 9800cm² = 98m²

Area of second type of box = 2(40x30 + 40x20  +  30x20)

= 2(1200 + 800 + 600) = 2x 2600 = 5200cm² = 52m²

Total area = 98 + 52 = 150

Area of second type of 300 boxes = 150 x 300 = 45000m²

Area wasted = 45000 x 10/100 = 4500

Total are  = 45000 + 4500 = 49500m²

Rate for per m² = Rs.20

Rate for 49500m² = 49500 x 20 = Rs. 990,000
