A tank with a square base of 30 cm was
14 filled with water After another 18270 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 18270 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 18270
112 of the tank = 18270 ÷ 7 = 2610
1212 of the tank = 12 x 2610 = 31320
31320 mℓ = 31.32 ℓ
Capacity of the tank = 31.32 ℓ
(b)
1012 of the tank = 10 x 2610 = 26100
Final height of the water in the tank
=
2610030 x 30 = 29 cm
Answer(s): (a) 31.32 ℓ; (b) 29 cm
