A tank with a square base of 20 cm was
14 filled with water After another 13200 cm
3 of water was poured into the tank, it became
45 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 13200 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 13200
120 of the tank = 13200 ÷ 11 = 1200
2020 of the tank = 20 x 1200 = 24000
24000 mℓ = 24 ℓ
Capacity of the tank = 24 ℓ
(b)
1620 of the tank = 16 x 1200 = 19200
Final height of the water in the tank
=
1920020 x 20 = 48 cm
Answer(s): (a) 24 ℓ; (b) 48 cm
