A tank with a square base of 10 cm was
38 filled with water After another 4235 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 4235 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 4235
124 of the tank = 4235 ÷ 11 = 385
2424 of the tank = 24 x 385 = 9240
9240 mℓ = 9.24 ℓ
Capacity of the tank = 9.24 ℓ
(b)
2024 of the tank = 20 x 385 = 7700
Final height of the water in the tank
=
770010 x 10 = 77 cm
Answer(s): (a) 9.24 ℓ; (b) 77 cm
