A tank with a square base of 30 cm was
15 filled with water After another 30360 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 30360 cm
3 of water was poured into the tank
=
34 -
15=
1520 -
420=
11201120 of the tank = 30360
120 of the tank = 30360 ÷ 11 = 2760
2020 of the tank = 20 x 2760 = 55200
55200 mℓ = 55.2 ℓ
Capacity of the tank = 55.2 ℓ
(b)
1520 of the tank = 15 x 2760 = 41400
Final height of the water in the tank
=
4140030 x 30 = 46 cm
Answer(s): (a) 55.2 ℓ; (b) 46 cm
