A tank with a square base of 30 cm was
15 filled with water After another 43560 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 43560 cm
3 of water was poured into the tank
=
34 -
15=
1520 -
420=
11201120 of the tank = 43560
120 of the tank = 43560 ÷ 11 = 3960
2020 of the tank = 20 x 3960 = 79200
79200 mℓ = 79.2 ℓ
Capacity of the tank = 79.2 ℓ
(b)
1520 of the tank = 15 x 3960 = 59400
Final height of the water in the tank
=
5940030 x 30 = 66 cm
Answer(s): (a) 79.2 ℓ; (b) 66 cm
