What is the least number of Identical cuboids, each of dimensions 2cm*4cm*5cm, that are required to form a cube

• 200 cuboids required to form a cube (Least Number).
  
  By taking L.C.M of dimension 2cm*4cm*5cm,
  we get 20 will be the side of cube of minimum dimensions.
  So,
  Number of minimum cuboids = (20*20*20)/(2*4*5)
  = 10*20
  = 200 cuboids.

• volume of cuboid =40 cm3
  to form a cube we need 10 cuboids whose collective volume will be 1000 cm3.
  which is the cube of 10cm3.
  so, 25 will be the min number of cuboids.

• Number of minimum cuboids = (20*20*20)/(2*4*5)
  = 10*20
  = 200 cuboids.
