A tank with a square base of 30 cm was
13 filled with water After another 20000 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 20000 cm
3 of water was poured into the tank
=
34 -
13=
912 -
412=
512512 of the tank = 20000
112 of the tank = 20000 ÷ 5 = 4000
1212 of the tank = 12 x 4000 = 48000
48000 mℓ = 48 ℓ
Capacity of the tank = 48 ℓ
(b)
912 of the tank = 9 x 4000 = 36000
Final height of the water in the tank
=
3600030 x 30 = 40 cm
Answer(s): (a) 48 ℓ; (b) 40 cm
