A tank with a square base of 10 cm was
14 filled with water After another 3710 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 3710 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 3710
112 of the tank = 3710 ÷ 7 = 530
1212 of the tank = 12 x 530 = 6360
6360 mℓ = 6.36 ℓ
Capacity of the tank = 6.36 ℓ
(b)
1012 of the tank = 10 x 530 = 5300
Final height of the water in the tank
=
530010 x 10 = 53 cm
Answer(s): (a) 6.36 ℓ; (b) 53 cm
