Question

There is some water in a cylindrical vessel of base diameter 14 cm when an iron cube is entirely immersed in it the height of water rises by 8 9 by 14 cm find the length of edge of the cube

Answer 1

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

Answer 2

Step-by-step explanation:

length of edge of the cube =11 cm
