35 of a container is filled with water. Another 92 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 -
35 =
25 25 of the tank = 92 ℓ
15 of the tank = 92 ÷ 2 = 46 ℓ
55 of the tank = 46 x 5 = 230 ℓ
230 ℓ = 230000 mℓ
(b)
Length of the container
= 230000 ÷ (40 x 50)
= 115 cm
Perimeter of the base
= (115 + 50) x 2
= 330 cm
Answer(s): (a) 230000 mℓ; (b) 330 cm
