Question

A 25/9
B 125/9
C 32
D 64

Answer 1

Length = 5 feet

Breadth = (5/3) feet

Height(depth) = 2 feet

Volume of the entire tank = Length x Breadth x Height

=
`5 * (5)/(3) *2 = (50)/(3)` ----------(1)

Water is filled upto a height of (1/3) feet

Volume of water in the tank = Length x Breadth x Height

=
`5 * (5)/(3) * (1)/(3) = (25)/(9)` -------------(2)

Volume of space needed to be filled = (1) - (2)

=
`(50)/(3) -(25)/(9) = (150-25)/(9) = (125)/(9) cubic feet`

OR

Height of tank needed to be filled = 2 - (1/3) = (5/3) feet

Volume of space = Length x Breadth x Height of empty tank

=
`5 * (5)/(3) * (5)/(3) = (125)/(9) cubic \ feet`
