A tank with a square base of 30 cm was
25 filled with water After another 23520 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 23520 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 23520
120 of the tank = 23520 ÷ 7 = 3360
2020 of the tank = 20 x 3360 = 67200
67200 mℓ = 67.2 ℓ
Capacity of the tank = 67.2 ℓ
(b)
1520 of the tank = 15 x 3360 = 50400
Final height of the water in the tank
=
5040030 x 30 = 56 cm
Answer(s): (a) 67.2 ℓ; (b) 56 cm
