A tank with a square base of 30 cm was
14 filled with water After another 13125 cm
3 of water was poured into the tank, it became
35 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 13125 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 13125
120 of the tank = 13125 ÷ 7 = 1875
2020 of the tank = 20 x 1875 = 37500
37500 mℓ = 37.5 ℓ
Capacity of the tank = 37.5 ℓ
(b)
1220 of the tank = 12 x 1875 = 22500
Final height of the water in the tank
=
2250030 x 30 = 25 cm
Answer(s): (a) 37.5 ℓ; (b) 25 cm
