35 of a container is filled with water. Another 114 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 38 cm and its breadth is 60 cm. Find the perimeter of its base.
(a)
Fraction of the container not filled with water = 1 -
35 =
25 25 of the tank = 114 ℓ
15 of the tank = 114 ÷ 2 = 57 ℓ
55 of the tank = 57 x 5 = 285 ℓ
285 ℓ = 285000 mℓ
(b)
Length of the container
= 285000 ÷ (38 x 60)
= 125 cm
Perimeter of the base
= (125 + 60) x 2
= 370 cm
Answer(s): (a) 285000 mℓ; (b) 370 cm
