A solid cylinder of diameter D and height equal to diameter and a solid cube of side a are being sand casted by using same material. The ratio of solidification time of the cylinder to the solidification time of the cube is
1
\({\left( {\frac{a}{D}} \right)^2}\)
2
\({\left( {\frac{{2a}}{D}} \right)^2}\)
3
\({\left( {\frac{{2D}}{a}} \right)^2}\)
4
\({\left( {\frac{D}{a}} \right)^2}\)
