35 of a container is filled with water. Another 108 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 = 108 ℓ
15 of the tank = 108 ÷ 2 = 54 ℓ
55 of the tank = 54 x 5 = 270 ℓ
270 ℓ = 270000 mℓ
(b)
Length of the container
= 270000 ÷ (40 x 50)
= 135 cm
Perimeter of the base
= (135 + 50) x 2
= 370 cm
Answer(s): (a) 270000 mℓ; (b) 370 cm
