58 of a container is filled with water. Another 102 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 = 102 ℓ
18 of the tank = 102 ÷ 3 = 34 ℓ
88 of the tank = 34 x 8 = 272 ℓ
272 ℓ = 272000 mℓ
(b)
Length of the container
= 272000 ÷ (40 x 50)
= 136 cm
Perimeter of the base
= (136 + 50) x 2
= 372 cm
Answer(s): (a) 272000 mℓ; (b) 372 cm
