Answer:

Step-by-step explanation:

For cuboid,

length (l) = 12+12+12 = 36cm

Breath (b) = 12cm

height (h) = 12cm

T.S.A of cuboid = 2(lb+bh+hl)

= 2(36×12+12×12+12×36)

= 2(432+144+432)

= 2×1008 = 2016 square cm

Answer:

ANSWER

Length of the resulting cuboid

=(12+12)cm

=24cm

Breadth and height remaining the same i.e. 12 cm eachSurface area =2(lb+bh+lh)

=2(24×12+12×12+24×12)cm

2

• =1440cm
