A tank with a square base of 40 cm was
38 filled with water After another 24000 cm
3 of water was poured into the tank, it became
34 full.
- Find the capacity of the tank in litres.
- Find the final height of the water in the tank.
(a)
Fraction of the tank when 24000 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 24000
18 of the tank = 24000 ÷ 3 = 8000
88 of the tank = 8 x 8000 = 64000
64000 mℓ = 64 ℓ
Capacity of the tank = 64 ℓ
(b)
68 of the tank = 6 x 8000 = 48000
Final height of the water in the tank
=
4800040 x 40 = 30 cm
Answer(s): (a) 64 ℓ; (b) 30 cm
