A tank with a square base of 10 cm was
38 filled with water After another 750 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 750 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 750
18 of the tank = 750 ÷ 3 = 250
88 of the tank = 8 x 250 = 2000
2000 mℓ = 2 ℓ
Capacity of the tank = 2 ℓ
(b)
68 of the tank = 6 x 250 = 1500
Final height of the water in the tank
=
150010 x 10 = 15 cm
Answer(s): (a) 2 ℓ; (b) 15 cm
