A tank with a square base of 40 cm was
13 filled with water After another 58800 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 58800 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 58800
115 of the tank = 58800 ÷ 7 = 8400
1515 of the tank = 15 x 8400 = 126000
126000 mℓ = 126 ℓ
Capacity of the tank = 126 ℓ
(b)
1215 of the tank = 12 x 8400 = 100800
Final height of the water in the tank
=
10080040 x 40 = 63 cm
Answer(s): (a) 126 ℓ; (b) 63 cm
