A tank with a square base of 10 cm was
14 filled with water After another 3010 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 3010 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 3010
112 of the tank = 3010 ÷ 7 = 430
1212 of the tank = 12 x 430 = 5160
5160 mℓ = 5.16 ℓ
Capacity of the tank = 5.16 ℓ
(b)
1012 of the tank = 10 x 430 = 4300
Final height of the water in the tank
=
430010 x 10 = 43 cm
Answer(s): (a) 5.16 ℓ; (b) 43 cm
