58 of a container is filled with water. Another 120 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 32 cm and its breadth is 50 cm. Find the perimeter of its base.
(a)
Fraction of the container not filled with water = 1 -
58 =
38 38 of the tank = 120 ℓ
18 of the tank = 120 ÷ 3 = 40 ℓ
88 of the tank = 40 x 8 = 320 ℓ
320 ℓ = 320000 mℓ
(b)
Length of the container
= 320000 ÷ (32 x 50)
= 200 cm
Perimeter of the base
= (200 + 50) x 2
= 500 cm
Answer(s): (a) 320000 mℓ; (b) 500 cm
