A tank with a square base of 40 cm was
14 filled with water After another 28600 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 28600 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 28600
120 of the tank = 28600 ÷ 11 = 2600
2020 of the tank = 20 x 2600 = 52000
52000 mℓ = 52 ℓ
Capacity of the tank = 52 ℓ
(b)
1620 of the tank = 16 x 2600 = 41600
Final height of the water in the tank
=
4160040 x 40 = 26 cm
Answer(s): (a) 52 ℓ; (b) 26 cm
