The question reads: "During solidification of molten metal, the Cube shaped casting takes _______ time to solidify compared to that of a Spherical casting of the same volume." The answer choices are: - equal - more - None of the above. - lesser **Correct Answer: more** ### Explanation: A spherical shape has the minimum surface area for a given volume, which allows heat to escape more slowly, resulting in a longer solidification time. A cube, having a greater surface area for the same volume, loses heat faster and thus **solidifies in less time** compared to a sphere. However, the question asks **which takes more time**. For the same volume, the sphere takes more time to solidify than the cube. So, the cube takes **less** time. **So the correct answer is: "lesser"**. #### Corrected Answer: - **lesser**
