Question

15. A tin box of 1 m length, 85 cm width and 60 cm depth is to be made. If the box is without top, find the area of the tin required to make the box and the cost of tin at the rate of rupees 0.50 per sq. cm...​

Answer 1

Answer:

L = 100cm

L = 85cm

L = 60 cm

Surface area of box = lateral surface area of cuboid + base area = 2h ( L + b) + Lb = 2 * 60* ( 100 + 85 ) + 100*85

= 120*185+8500

= 30700cm²

cost of tin : - 30700*0.5 = 15350₹
