Two cubes of sides 6 cm each are kept side by side to form a rectangular parallelopiped. The area (in sq. cm) of the whole surface of the rectangular parallelopiped is

a

432

b

360

c

396

d

340

Answer : Option B
Explanation :

Length of parallelopiped = 12 cm.

breadth = 6 cm.

height = 6 cm.

∴ Total surface area

= 2 (12 × 6 + 6 × 6 + 12 × 6) sq.cm.

= 2 (72 + 36 + 72) sq.cm.

= 360 sq.cm.
