Question

Find total surface area of cold whose dimension are 2m, 80cm and 60cm?​

Answer 1

Step-by-step explanation:

T. S. A = 2(lb+bh+lh)

=2(2×0.8+0.8×0.6+0.6×2)

=2(3.28)

=6.56 m square

Answer 2

Correct Question :-

Find total surface area of cuboid whose dimension are 2m, 80cm and 60cm.

Answer :-

• The total surface area of cuboid is 65600cm².

Step-by-step explanation :

To Find :-

• The total surface area of cuboid

Solution :-

Given that,

• The dimensions of the cuboid is 2m*80cm*60cm.

First, we need to convert 2m to cm,

=> ( 2 × 100 )cm

=> 200cm.

Hence,

• Length of cuboid = 200cm
• Breadth of cuboid = 80cm
• Height of cuboid = 60cm.

Therefore, According the question, the total surface area of cuboid is,

As we know that,

Total surface area of cuboid = 2 ( lb + bh + hl ) sq. units,

=> 2 ( lb + bh + hl )

=> 2 ( 200*80 + 80*60 + 60*200 )

=> 2 ( 16000 + 4800 + 12000 )

=> 2 ( 20800 + 12000 )

=> 2 ( 32800 )

=> 2*32800

=> 65600

• The total surface area of cuboid is 65600cm².
