A tank with a square base of 40 cm was
14 filled with water After another 68200 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 68200 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 68200
120 of the tank = 68200 ÷ 11 = 6200
2020 of the tank = 20 x 6200 = 124000
124000 mℓ = 124 ℓ
Capacity of the tank = 124 ℓ
(b)
1620 of the tank = 16 x 6200 = 99200
Final height of the water in the tank
=
9920040 x 40 = 62 cm
Answer(s): (a) 124 ℓ; (b) 62 cm
