Question

A box which measure 70 cm*36 cm*12 cm is to be covered with canvas. how many meters of canvas of width 80 cm would be required to cover 150 such boxes?

Answer 1

Heya Frnd.........☺

TSA of 1 box = l×b×h

=> 70 × 36 × 12

=> 30,240 cm²

So,

TSA of 150 boxes => 4536000 cm²

NOW,

Length of cloth = TSA of 150 boxes

=> 80 × l = 4536000

=> l = 4536000/80

$= > \boxed{567000 \: cm}$
