A tank with a square base of 10 cm was
25 filled with water After another 1540 cm
3 of water was poured into the tank, it became
34 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 1540 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 1540
120 of the tank = 1540 ÷ 7 = 220
2020 of the tank = 20 x 220 = 4400
4400 mℓ = 4.4 ℓ
Capacity of the tank = 4.4 ℓ
(b)
1520 of the tank = 15 x 220 = 3300
Final height of the water in the tank
=
330010 x 10 = 33 cm
Answer(s): (a) 4.4 ℓ; (b) 33 cm
