answered-by-expert Expert Answer

volume of cistern = 150.120.110 = 1980000 cm3

volume of water in cistern = 129600 cm3

volume available for bricks = 1980000-129600 = 1850400 cm3

volume of one brick = 22.5*7.5*6.5 = 1096.875 cm3

volume occupied by one brick = 1096.875 / 17 cm3 

so no. of bricks that can be placed without overflow = 1850400 / (1096.875 /17) = (1850400*17) / (1096.875) = 28678.56

i.e. we can place 28678 bricks without overflow.
