58 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 40 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 = 114 ℓ
18 of the tank = 114 ÷ 3 = 38 ℓ
88 of the tank = 38 x 8 = 304 ℓ
304 ℓ = 304000 mℓ
(b)
Length of the container
= 304000 ÷ (40 x 50)
= 152 cm
Perimeter of the base
= (152 + 50) x 2
= 404 cm
Answer(s): (a) 304000 mℓ; (b) 404 cm
