A tank with a square base of 50 cm was
14 filled with water After another 31500 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 31500 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 31500
112 of the tank = 31500 ÷ 7 = 4500
1212 of the tank = 12 x 4500 = 54000
54000 mℓ = 54 ℓ
Capacity of the tank = 54 ℓ
(b)
1012 of the tank = 10 x 4500 = 45000
Final height of the water in the tank
=
4500050 x 50 = 18 cm
Answer(s): (a) 54 ℓ; (b) 18 cm
