Answer 1

Thank you for asking this question. Here is your answer:

First of all we will calculate the volume of metal which is used:

22 [8²-7²] 35/7

= 22[64-49] 5

= 110 x 15

= 1650 cu cm

We know that the weight of metal/cm³ is 10gm

1650 cm cube = 1650 x 10

= 16500 gm

= 16.500 kg

If there is any confusion please leave a comment below.
