A tank with a square base of 20 cm was
14 filled with water After another 7975 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 7975 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 7975
120 of the tank = 7975 ÷ 11 = 725
2020 of the tank = 20 x 725 = 14500
14500 mℓ = 14.5 ℓ
Capacity of the tank = 14.5 ℓ
(b)
1620 of the tank = 16 x 725 = 11600
Final height of the water in the tank
=
1160020 x 20 = 29 cm
Answer(s): (a) 14.5 ℓ; (b) 29 cm
