Tank J was
16 filled with water. After 20000 cm
3 of water was added to Tank J, it became
712 full.
- Find the volume of Tank J in litres.
- Find the volume of water in Tank J in the end. Give your answer in litres.
(a)
Fraction of the tank when 20000 cm
3 of water was added into Tank J
=
712 -
16 =
712 -
212 =
512 512 of the tank = 20000
112 of the tank = 20000 ÷ 5 = 4000
1212 of the tank = 12 x 4000 = 48000
48000 mℓ = 48 ℓ
Capacity of the tank = 48 ℓ
(b)
Volume of water in Tank J in the end
=
712 x 48
= 28 ℓ
Answer(s): (a) 48 ℓ ; (b) 28 ℓ
