A tank with a square base of 40 cm was
14 filled with water After another 42560 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 42560 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 42560
112 of the tank = 42560 ÷ 7 = 6080
1212 of the tank = 12 x 6080 = 72960
72960 mℓ = 72.96 ℓ
Capacity of the tank = 72.96 ℓ
(b)
1012 of the tank = 10 x 6080 = 60800
Final height of the water in the tank
=
6080040 x 40 = 38 cm
Answer(s): (a) 72.96 ℓ; (b) 38 cm
