A tank with a square base of 20 cm was
38 filled with water After another 8400 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 8400 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 8400
18 of the tank = 8400 ÷ 3 = 2800
88 of the tank = 8 x 2800 = 22400
22400 mℓ = 22.4 ℓ
Capacity of the tank = 22.4 ℓ
(b)
68 of the tank = 6 x 2800 = 16800
Final height of the water in the tank
=
1680020 x 20 = 42 cm
Answer(s): (a) 22.4 ℓ; (b) 42 cm
