# Two equal cubes with sides 6 cm are placed one above the other, forming a cuboid. Find the total surface area of the cuboid thus formed.

Answer :

Side of the cube = 6 cm

.

Breadth of the cuboid = 6 cm

and height = 6 cm

Total surface area = 2(lb + bh + hl)

= 2(12 x 6 + 6 x 6 + 6 x 12)

= 360 cm

.

^{.}. Length of the cuboid = 6 + 6 = 12 cmBreadth of the cuboid = 6 cm

and height = 6 cm

Total surface area = 2(lb + bh + hl)

= 2(12 x 6 + 6 x 6 + 6 x 12)

= 360 cm
