A tank with a square base of 20 cm was
38 filled with water After another 7040 cm
3 of water was poured into the tank, it became
56 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 7040 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 7040
124 of the tank = 7040 ÷ 11 = 640
2424 of the tank = 24 x 640 = 15360
15360 mℓ = 15.36 ℓ
Capacity of the tank = 15.36 ℓ
(b)
2024 of the tank = 20 x 640 = 12800
Final height of the water in the tank
=
1280020 x 20 = 32 cm
Answer(s): (a) 15.36 ℓ; (b) 32 cm
