35 of a container is filled with water. Another 112 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 -
35 =
25 25 of the tank = 112 ℓ
15 of the tank = 112 ÷ 2 = 56 ℓ
55 of the tank = 56 x 5 = 280 ℓ
280 ℓ = 280000 mℓ
(b)
Length of the container
= 280000 ÷ (32 x 50)
= 175 cm
Perimeter of the base
= (175 + 50) x 2
= 450 cm
Answer(s): (a) 280000 mℓ; (b) 450 cm
