Volume of a cube of side ‘l’ and volume of a sphere of radius ‘r’ are equal . Both the cube and the sphere are solid and of same material.They are being cast . The ratio of solidification time of the cube to the sphere is given by ;
1
\( \left(\frac{4\pi }{6}\right)^3\left(\frac{ r}{l}\right)^6\)
2
\( \left(\frac{4\pi }{6}\right)\left(\frac{ r}{l}\right)^2\)
3
\( \left(\frac{4\pi }{6}\right)^2\left(\frac{ r}{l}\right)^3\)
4
\( \left(\frac{4\pi }{6}\right)^2\left(\frac{ r}{l}\right)^4\)
