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?
Read Solution (Total 10)
-
- 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 - 12 years agoHelpfull: Yes(5) No(1)
- 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 - 9 years agoHelpfull: Yes(2) No(0)
- Answer :6*12*6=432 cubic cm
here length=12,breath=6,height=6 - 12 years agoHelpfull: Yes(0) No(1)
- 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 - 9 years agoHelpfull: Yes(0) No(0)
- 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 - 8 years agoHelpfull: Yes(0) No(0)
- 6+6=12cm will bethe width of rectangle
and hight of rectangle is 6cm
so area of rectangle =12*6=72 - 7 years agoHelpfull: Yes(0) No(0)
