Tank W was
14 filled with water. After 20000 cm
3 of water was added to Tank W, it became
78 full.
- Find the volume of Tank W in litres.
- Find the volume of water in Tank W in the end. Give your answer in litres.
(a)
Fraction of the tank when 20000 cm
3 of water was added into Tank W
=
78 -
14 =
78 -
28 =
58 58 of the tank = 20000
18 of the tank = 20000 ÷ 5 = 4000
88 of the tank = 8 x 4000 = 32000
32000 mℓ = 32 ℓ
Capacity of the tank = 32 ℓ
(b)
Volume of water in Tank W in the end
=
78 x 32
= 28 ℓ
Answer(s): (a) 32 ℓ ; (b) 28 ℓ
