because TSA of cuboid is 30×15×20 = 9000cm sq.

and then its divide the whole TSA of metal sheet that is 27000cm sq.

27000÷9000= 3

so 3 boxes are made in one minute

Answer 2

Answer:

60 boxes

Step-by-step explanation:

Length = 30 cm

Width = 15 cm

∴ Area of each box = (30 x 15)cm² = 450cm²

Area of thin metal used in a minute = 27000 cm²

∴ No. of boxes made in a minute = (27000 ÷ 450) = 60

Ans:- 60 boxes are made in a minute.
