  Volume of cube formed = n × volume of one cuboid

  (a)³ = n × (l×b×h)

  As per the question

  (a)³ = n × (5cm ×2cm ×5cm)

  Now we’ve to make a perfect cube on right hand side

  For that n must be equals to 5×2×2

  Therefore,

  n= 20

  We’ll need 20 such cuboids

  To form one cube.

  And the volume of formed cube would be 5000cm³.
