Question

a glass cylinder with diameter 20 cm has water to a height of 9 cm.A metallic cube of 8 cm edge is immersed in it completely.calculate the height by which water will rise in the cylinder

Answer 1

Diameter of cylinder = 20cm
Radius = 10cm
Height of glass = 9cm
Volume of cylindrical glass = πr²h
= 22/7×10×10×9 = 2828.57cm³
Edge of cube = 8cm
Volume of cube = a³ = (8)³ = 512cm³
Height of water after immersing the cube = Volume of glass + volume of cube = 2828.57+ 512 = 3340.57
