A tank with a square base of 30 cm was
25 filled with water After another 14700 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 14700 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 14700
120 of the tank = 14700 ÷ 7 = 2100
2020 of the tank = 20 x 2100 = 42000
42000 mℓ = 42 ℓ
Capacity of the tank = 42 ℓ
(b)
1520 of the tank = 15 x 2100 = 31500
Final height of the water in the tank
=
3150030 x 30 = 35 cm
Answer(s): (a) 42 ℓ; (b) 35 cm
