A cuboid of length 4 cm,breadth 6 cm and height 8 cm is formed using units cubes.All the faces of the cuboid are painted using different colours.now the cubes are seperated and the cubes with no face painted are used to form a new cuboid.Find the volume of a new formed cuboid.

• 48cc.
  unit cubes at the edges are chopped off.
  length, breadth and height are reduced by 2 units (1 at each of the ends)
  therefore volume of the new cube=2*4*6=48

• volume of it =4*6*8=192
  unit cubes are used,so no. of cubes=192/(1*1*1)=192 no. of cubes.
  now there are 8 layers of cuboid of its lenght=4cm and breadth=6cm
  hence all the faces of cuboid are painted using diffrent coliurs ,
  so no of cubes with no face painted--
  in 1st layer=0
  in 2nd layer to 7th layer=6*8=48
  in 8th or last layer=0
  so total no of cubes with no face painted =48
  so the volume of new formed cuboid is 48 cm^3

• Cuboid is made of unit cubes
  Find the volume of hollow cuboid = (4-2)*(6-2)*(8-2)
  = 2*4*6
  = 48

• Can some1 explain it clearly in detail..and how can u say "unit cubes at the edges are chopped off?"

• length 2 cm, breadth 4 cm and height 6 cm.
  As we can see cube have three different size faces 4*6, 6*8 and 4*8
  And we can get tyhat when we paint the cuboid from one side. the inner unpainted surfac dimension will be
  for 4*6 it will be 2*4
  for 6*8 it will be 4*6
  and for 4*8 it will be 2*6
  so we get the new unpainted cuboid have a dimension of 2*4*6
