Question:
Aluminium is casted in a cube-shaped mold having dimensions as 20mm × 20mm × 20mm. Another mold of the same mold material is used to cast a sphere of aluminium having a diameter of 20mm. The pouring temperature for both cases is the same. The ratio of the solidification times of the cube-shaped mold to the spherical mold is ____ (answer in integer).

Top Questions on Solidification and cooling
- The solidification time of a cube and a cylinder of the same material, produced through the same sand casting process, is found to be equal. Each side of the cube is \(a\), and the radius and the length of the cylinder are \(r\) and \(4r\), respectively. If the solidification time is governed by Chvorinov's equation, then the ratio \(\frac ra\) is
