A tank with a square base of 50 cm was
14 filled with water After another 89250 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 89250 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 89250
112 of the tank = 89250 ÷ 7 = 12750
1212 of the tank = 12 x 12750 = 153000
153000 mℓ = 153 ℓ
Capacity of the tank = 153 ℓ
(b)
1012 of the tank = 10 x 12750 = 127500
Final height of the water in the tank
=
12750050 x 50 = 51 cm
Answer(s): (a) 153 ℓ; (b) 51 cm
