Question

the dimension fo an oil tin are 26 cm×26cm×45cm find the area of tin sheet required to make 20 such tin

Answer 1

Length= 26 cm
Breadth= 26 cm
Height=45 cm
Total Surface Area = 2(lb+bh+lh)
= 2(676cm²+1170cm²+1170cm²)
= 2*3016cm²
= 6032cm²
Area of 20 such tins = 6032cm²*20
= 120640cm²

Answer 2

Heya mate,
Here is your answer,

oil tin's,
length = l = 26cm
breadth = b = 26cm
height = h = 45cm

tin sheet for one can = TSA of the can
= 2( lb + bh + hl )
= 2( 26×26 + 26×45 + 45×26 )
= 2( 676 + 1170 + 1170 )
= 2 × 3016
= 6032cm²

tin sheet for 20 such cans = 20×TSA
= 20 × 6032
= 120640cm²

1m = 100cm
1m² = 10000cm²
1cm² = 1/10000 m²
So 120640cm² = 12.0640 m²

Hence 12.06 m² tin sheets would be used.

Hope this helps,

If you need further help or have any doubt ask me frankly. i would like to help.

Thank you
