A tank with a square base of 40 cm was
25 filled with water After another 8960 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 8960 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 8960
120 of the tank = 8960 ÷ 7 = 1280
2020 of the tank = 20 x 1280 = 25600
25600 mℓ = 25.6 ℓ
Capacity of the tank = 25.6 ℓ
(b)
1520 of the tank = 15 x 1280 = 19200
Final height of the water in the tank
=
1920040 x 40 = 12 cm
Answer(s): (a) 25.6 ℓ; (b) 12 cm
