A tank with a square base of 40 cm was
13 filled with water After another 47600 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 47600 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 47600
115 of the tank = 47600 ÷ 7 = 6800
1515 of the tank = 15 x 6800 = 102000
102000 mℓ = 102 ℓ
Capacity of the tank = 102 ℓ
(b)
1215 of the tank = 12 x 6800 = 81600
Final height of the water in the tank
=
8160040 x 40 = 51 cm
Answer(s): (a) 102 ℓ; (b) 51 cm
