A tank with a square base of 40 cm was
38 filled with water After another 50400 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 50400 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 50400
18 of the tank = 50400 ÷ 3 = 16800
88 of the tank = 8 x 16800 = 134400
134400 mℓ = 134.4 ℓ
Capacity of the tank = 134.4 ℓ
(b)
68 of the tank = 6 x 16800 = 100800
Final height of the water in the tank
=
10080040 x 40 = 63 cm
Answer(s): (a) 134.4 ℓ; (b) 63 cm
