A tank with a square base of 30 cm was
14 filled with water After another 14490 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 14490 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 14490
112 of the tank = 14490 ÷ 7 = 2070
1212 of the tank = 12 x 2070 = 24840
24840 mℓ = 24.84 ℓ
Capacity of the tank = 24.84 ℓ
(b)
1012 of the tank = 10 x 2070 = 20700
Final height of the water in the tank
=
2070030 x 30 = 23 cm
Answer(s): (a) 24.84 ℓ; (b) 23 cm
