A tank with a square base of 20 cm was
15 filled with water After another 20240 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 20240 cm
3 of water was poured into the tank
=
34 -
15=
1520 -
420=
11201120 of the tank = 20240
120 of the tank = 20240 ÷ 11 = 1840
2020 of the tank = 20 x 1840 = 36800
36800 mℓ = 36.8 ℓ
Capacity of the tank = 36.8 ℓ
(b)
1520 of the tank = 15 x 1840 = 27600
Final height of the water in the tank
=
2760020 x 20 = 69 cm
Answer(s): (a) 36.8 ℓ; (b) 69 cm
