A tank with a square base of 30 cm was
14 filled with water After another 10710 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 10710 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 10710
112 of the tank = 10710 ÷ 7 = 1530
1212 of the tank = 12 x 1530 = 18360
18360 mℓ = 18.36 ℓ
Capacity of the tank = 18.36 ℓ
(b)
1012 of the tank = 10 x 1530 = 15300
Final height of the water in the tank
=
1530030 x 30 = 17 cm
Answer(s): (a) 18.36 ℓ; (b) 17 cm
