Answer 1

Answer:

first find the total surface area of the cuboid whose measurements are 6cm, 3cm, and 2cm.

TSA = 2 (lb+bh+hl)

        = 2 [ (6*3) + (3*2) + (6*2)]

        = 2 [ 18 + 6 + 12 ]

        = 2 [ 36 ]

        = 72 cm² ..............i

now, we find the TSA of the second cuboid whose sides measure 1cm, 3cm and 2cm.

TSA = 2 (lb+bh+hl)

       = 2 [ (1*3) + (3*2) + (2*1) ]

       = 2 [ 3 + 6 + 2 ]

       = 2 [ 11 ]

       = 22cm²...................ii

By adding i and ii we will get the final answer

= 22cm² + 72cm²

= 94cm²
