Are of cuboibd= Tsa of 2 cubes - 2 joining sufaces.
A= 6(6s^2)-2(s^2)
=6(6×100)-2(100)
=3600-200
=3400cm^2
A= 6(6s^2)-2(s^2)

Given:
Side of both two cubes =10cm
:After joining both two cubes.
Length=10cm+10cm=20cm
Breadth =10cm
Height =10cm
We know :
:Total Surface area of cuboid =2(lb+bh+hl)
=2(200cm2+100cm2+200cm2)
=2(500cm2)
=1,000cm2
Lateral surface area of cuboid =2(l+b)h
=2(20cm+10cm)10cm
=(60cm)10cm
=600cm2
Hope it help you.
