A tank with a square base of 10 cm was
14 filled with water After another 1260 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 1260 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 1260
112 of the tank = 1260 ÷ 7 = 180
1212 of the tank = 12 x 180 = 2160
2160 mℓ = 2.16 ℓ
Capacity of the tank = 2.16 ℓ
(b)
1012 of the tank = 10 x 180 = 1800
Final height of the water in the tank
=
180010 x 10 = 18 cm
Answer(s): (a) 2.16 ℓ; (b) 18 cm
