35 of a container is filled with water. Another 104 litres of water are needed to fill the container to its brim.
- What is the volume of the container in mℓ?
- The height of the container is 40 cm and its breadth is 50 cm. Find the perimeter of its base.
(a)
Fraction of the container not filled with water = 1 -
35 =
25 25 of the tank = 104 ℓ
15 of the tank = 104 ÷ 2 = 52 ℓ
55 of the tank = 52 x 5 = 260 ℓ
260 ℓ = 260000 mℓ
(b)
Length of the container
= 260000 ÷ (40 x 50)
= 130 cm
Perimeter of the base
= (130 + 50) x 2
= 360 cm
Answer(s): (a) 260000 mℓ; (b) 360 cm
