A tank with a square base of 30 cm was
15 filled with water After another 7260 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 7260 cm
3 of water was poured into the tank
=
34 -
15=
1520 -
420=
11201120 of the tank = 7260
120 of the tank = 7260 ÷ 11 = 660
2020 of the tank = 20 x 660 = 13200
13200 mℓ = 13.2 ℓ
Capacity of the tank = 13.2 ℓ
(b)
1520 of the tank = 15 x 660 = 9900
Final height of the water in the tank
=
990030 x 30 = 11 cm
Answer(s): (a) 13.2 ℓ; (b) 11 cm
