A tank with a square base of 40 cm was
14 filled with water After another 56100 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 56100 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 56100
120 of the tank = 56100 ÷ 11 = 5100
2020 of the tank = 20 x 5100 = 102000
102000 mℓ = 102 ℓ
Capacity of the tank = 102 ℓ
(b)
1620 of the tank = 16 x 5100 = 81600
Final height of the water in the tank
=
8160040 x 40 = 51 cm
Answer(s): (a) 102 ℓ; (b) 51 cm
