Question

A rectangular flask of length 11 cm, width 8 cm and height 20 cm has water filled up to height 5 cm. if 21 spherical marbles of radius 1 cm each are dropped in the flask, what would be the rise in water level?

Answer 1

Thank you for the question.yes the water level will raise . initially the volume of filled flask of water is l.b.h=440cm3 when 12 sphere of 1cm is added 88 cm3 then the volume increases

Answer 2

Answer:

Step-by-step explanation:

Volume of water in the flask = l*w*h

= 11*8*5 = 440

Volume of 21 spherical marbles = 4/3 * 22/7 * 1^3 * 21 = 88

Total volume in the flask becomes 440 + 88 = 528

528 = l * w*h

528= 11*8*h

h= 6 cm ( height after adding marbles)

Rise in water level= 6-5 = 1 cm
