A tank with a square base of 40 cm was
14 filled with water After another 50400 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 50400 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 50400
112 of the tank = 50400 ÷ 7 = 7200
1212 of the tank = 12 x 7200 = 86400
86400 mℓ = 86.4 ℓ
Capacity of the tank = 86.4 ℓ
(b)
1012 of the tank = 10 x 7200 = 72000
Final height of the water in the tank
=
7200040 x 40 = 45 cm
Answer(s): (a) 86.4 ℓ; (b) 45 cm
