A tank with a square base of 40 cm was
15 filled with water After another 14080 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 14080 cm
3 of water was poured into the tank
=
34 -
15=
1520 -
420=
11201120 of the tank = 14080
120 of the tank = 14080 ÷ 11 = 1280
2020 of the tank = 20 x 1280 = 25600
25600 mℓ = 25.6 ℓ
Capacity of the tank = 25.6 ℓ
(b)
1520 of the tank = 15 x 1280 = 19200
Final height of the water in the tank
=
1920040 x 40 = 12 cm
Answer(s): (a) 25.6 ℓ; (b) 12 cm
