SOLUTION :

Given :

Side of cube = 4 cm

On joining 2 cubes we get a cuboid whose  

Length,l = 4+ 4 = 8 cm

Height ,h = 4 cm

Breadth ,b = 4 cm

Required surface area of the resulting cuboid = surface area of new cuboid

= 2( lb + bh + hl)

= 2 ( 8 × 4 + 4 × 4 + 4 × 8)

= 2 ( 32 + 16 + 32)

= 2 × 80

= 160 cm².

Hence, the total surface area of the new solid form is 160 cm².
