Answer:
Answer:
length of edge of the cube = 11 cm
Step-by-step explanation:
Diameter of cylinder = 14 cm
Radius of cylinder = 14/2 = 7 cm
Height of water Raised = 8 9/14 = 121/14 cm
Volume of Water Displaced by iron cube
= π R² h
= (22/7) (7)² (121/14)
= 11 * 121 cm³
= 11 * 11 * 11 cm³
= 11³ cm³
Volume of iron cube = (length of edge of the cube)³
(length of edge of the cube)³ = 11³
=> length of edge of the cube = 11 cm
