When the two cubes are fixed together, the resulting solid is a cuboid.

Length of the cuboid, = 2 × edge of the cube = 2*4 = 8 cm

Breadth of the cube = 1 × edge of the cube = 4 cm

Height of the cube = 1 × edge of the cube = 4 cm

Total surface area of the cuboid = 2*(LB + BL + LH)

⇒ 2(8(4) + 4(4) + 4(8))

⇒ 2(32 + 16 + 32)

⇒ 2(80)

⇒ 160 sq cm

So, the total surface area of the cuboid is 160 sq cm
