sheet of width 94 cm is required to cover 50 such boxes​

Answer 1

Answer:

100m

Step-by-step explanation:

Find the total surface area of 1 box:

Total surface area = 2( 90x50 + 50x35 + 35x90) = 18800 cm²

Find the total surface area of 50 boxes:

1 box = 18800 cm²

50 boxes = 18800 x 50 = 940000 cm²

Find the length of the sheet needed:

Length = 940000 ÷ 94 = 10000 cm = 100 m
