A tank with a square base of 40 cm was
25 filled with water After another 24640 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 24640 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 24640
120 of the tank = 24640 ÷ 7 = 3520
2020 of the tank = 20 x 3520 = 70400
70400 mℓ = 70.4 ℓ
Capacity of the tank = 70.4 ℓ
(b)
1520 of the tank = 15 x 3520 = 52800
Final height of the water in the tank
=
5280040 x 40 = 33 cm
Answer(s): (a) 70.4 ℓ; (b) 33 cm
