A tank with a square base of 20 cm was
25 filled with water After another 13440 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 13440 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 13440
120 of the tank = 13440 ÷ 7 = 1920
2020 of the tank = 20 x 1920 = 38400
38400 mℓ = 38.4 ℓ
Capacity of the tank = 38.4 ℓ
(b)
1520 of the tank = 15 x 1920 = 28800
Final height of the water in the tank
=
2880020 x 20 = 72 cm
Answer(s): (a) 38.4 ℓ; (b) 72 cm
