A tank with a square base of 30 cm was
13 filled with water After another 35700 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 35700 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 35700
115 of the tank = 35700 ÷ 7 = 5100
1515 of the tank = 15 x 5100 = 76500
76500 mℓ = 76.5 ℓ
Capacity of the tank = 76.5 ℓ
(b)
1215 of the tank = 12 x 5100 = 61200
Final height of the water in the tank
=
6120030 x 30 = 68 cm
Answer(s): (a) 76.5 ℓ; (b) 68 cm
