A tank with a square base of 30 cm was
15 filled with water After another 34320 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 34320 cm
3 of water was poured into the tank
=
34 -
15=
1520 -
420=
11201120 of the tank = 34320
120 of the tank = 34320 ÷ 11 = 3120
2020 of the tank = 20 x 3120 = 62400
62400 mℓ = 62.4 ℓ
Capacity of the tank = 62.4 ℓ
(b)
1520 of the tank = 15 x 3120 = 46800
Final height of the water in the tank
=
4680030 x 30 = 52 cm
Answer(s): (a) 62.4 ℓ; (b) 52 cm
