A tank with a square base of 20 cm was
15 filled with water After another 10560 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 10560 cm
3 of water was poured into the tank
=
34 -
15=
1520 -
420=
11201120 of the tank = 10560
120 of the tank = 10560 ÷ 11 = 960
2020 of the tank = 20 x 960 = 19200
19200 mℓ = 19.2 ℓ
Capacity of the tank = 19.2 ℓ
(b)
1520 of the tank = 15 x 960 = 14400
Final height of the water in the tank
=
1440020 x 20 = 36 cm
Answer(s): (a) 19.2 ℓ; (b) 36 cm
