A tank with a square base of 30 cm was
14 filled with water After another 26460 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 26460 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 26460
112 of the tank = 26460 ÷ 7 = 3780
1212 of the tank = 12 x 3780 = 45360
45360 mℓ = 45.36 ℓ
Capacity of the tank = 45.36 ℓ
(b)
1012 of the tank = 10 x 3780 = 37800
Final height of the water in the tank
=
3780030 x 30 = 42 cm
Answer(s): (a) 45.36 ℓ; (b) 42 cm
