A spherical cannonball with a diameter of 28 cm is melted and recast into a rectangular block. The length and breadth of the block are 44 cm and 14 cm respectively. What is the height of the rectangular block? (Take π = 22/7)
Show answer & explanation
Correct answer: C
Explanation
Given:
Diameter of the sphere = 28 cm
Radius r = 14 cm
Length of the block = 44 cm
Width of the block = 14 cm
According to the formula:
Volume of the sphere = (4/3)πr³
Volume of the rectangular block = l × b × h
h = 18.67 cm
