A tank with a square base of 30 cm was
14 filled with water After another 45360 cm
3 of water was poured into the tank, it became
56 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 45360 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 45360
112 of the tank = 45360 ÷ 7 = 6480
1212 of the tank = 12 x 6480 = 77760
77760 mℓ = 77.76 ℓ
Capacity of the tank = 77.76 ℓ
(b)
1012 of the tank = 10 x 6480 = 64800
Final height of the water in the tank
=
6480030 x 30 = 72 cm
Answer(s): (a) 77.76 ℓ; (b) 72 cm
