A tank with a square base of 30 cm was
14 filled with water After another 20475 cm
3 of water was poured into the tank, it became
35 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 20475 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 20475
120 of the tank = 20475 ÷ 7 = 2925
2020 of the tank = 20 x 2925 = 58500
58500 mℓ = 58.5 ℓ
Capacity of the tank = 58.5 ℓ
(b)
1220 of the tank = 12 x 2925 = 35100
Final height of the water in the tank
=
3510030 x 30 = 39 cm
Answer(s): (a) 58.5 ℓ; (b) 39 cm
