Two cubes of sides 6 cm each are kept side by side to form a ractangular parallelepiped. the area of whole surface of the ractangular parrallelepiped is?

• Area of cube = 6 x 6^2 = 216 sq.cm
  
  Area of rectangular parallelepiped = (2*area of cube) - (area of two faces)
  => A = (2 x 216) - (2 x 6^2) = 360 sq.cm

• length become 12
  but breadth and height will remain same i.e 6
  
  so area is 2(lb+bh+hl)
  =2( 72+36+72 )
  =2*180
  =360

• Answer :6*12*6=432 cubic cm
  here length=12,breath=6,height=6

• There are 6 sides for this rectangular parallelopiped. two faces are square : 6*6
  4 faces are rectangle: 12*6. So 4 in all rectangular faces put together = 72* 4= 288
  All 2 square faces put together = 36*2 = 72
  Total surface area of this parellelopiped is 360 sq.cm

• When two cubes of equal given measurements are kept aligned together,it forms a cuboid with length = 12 cm,breadth = 6 cm and height = 6 cm.So,the area of the parallelpiped is 2(lb + bh + lh) = 2 (12.6 + 6.12 + 6.6) cm^2 = 2 (72 + 72 + 26) cm^2 = 2 (180) cm^2 = 360 cm^2.

• area of parallelepiped= 2(lb+bh+lh)
  =2(12*6+6*12+6*6)
  =2(72+72+36)
  =2(180)= 360 cm^2

• 360 square cm
  explanation:-
  360=6*6+6*6+12*6+12*6+12*6+12*6

• 6+6=12cm will bethe width of rectangle
  and hight of rectangle is 6cm
  
  so area of rectangle =12*6=72
