Question

a box which measures 70cm×36cm×12cm is to curved with canvas. How many meters of canvas of width 80cm would be required to cover 150 such boxes?​

Answer 1

Answer:

14220m

Step-by-step explanation:

Given length of the box = 70cm.

Given breadth of the box = 36cm.

Given height of the box = 12cm.

We know that Total Surface area = 2(lb + bh + lh)

                                                       = 2(70 * 36 + 36 * 12 + 12 * 70)

                                                       = 7584.

Given Width = 80cm.

Length of the canvas = 7584/80

                                   = 94.8cm.

Therefore the required length = 94.8 * 150

                                                  = 14220m.

Hope this helps!
