A tank with a square base of 10 cm was
13 filled with water After another 3325 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 3325 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 3325
115 of the tank = 3325 ÷ 7 = 475
1515 of the tank = 15 x 475 = 7125
7125 mℓ = 7.125 ℓ
Capacity of the tank = 7.125 ℓ
(b)
1215 of the tank = 12 x 475 = 5700
Final height of the water in the tank
=
570010 x 10 = 57 cm
Answer(s): (a) 7.125 ℓ; (b) 57 cm
