According to question ..
length of cuboid=12cm+12cm= 24cm
breadth of cuboid = 12cm
height of cuboid =12cm
T.S.A of cuboid =2(lb+bh+hl).
T.S.A =2( 24×12 + 12×12 + 12×24)
T.S.A.=2( 288 + 144 + 288 )
T.S.A= 2( 720 )
T.S.A=1440 cm.cm or cm^2
T.S.A of cuboid = 1440 cm .square

Answer:
if we attach the two cubes together,then its length became double i.e a=24 and breadth and height will be same i.e breadth= height=12..
area of cuboid =2(lb+bh+hl)
=2(24×12+12×12+24×12)
=2(288+144+288)
=2×720
=1440cm^2
Hope this ...answer will be correct...
