cast using sand casting process. The top face heat. Two cubes of same material and size are The solidification time of a casting is proportional where Vis the volume of the casting to and A is the total casting surface area losing beat. Two cubes of same material and size are of one of the cubes is completely insulated. The ratio of the solidification time for the cube with top face insulated to that of the other cube is 36 (b) 25 25 (a) 36 (c) 1 (d)
