Answer:
C:1L
Explanation:
The volume of a rectangular container can be calculated using the formula:
Volume = Base Area × Height
Given the base area of the container is 200 cm² and its height is initially 15 cm, we can calculate the initial volume of water in the container:
Initial Volume = Base Area × Initial Height
Initial Volume = 200 cm² × 15 cm
Initial Volume = 3000 cm³
Now, the container's height is increased to 20 cm. To calculate the new volume after increasing the height, we'll use the same formula:
New Volume = Base Area × New Height
New Volume = 200 cm² × 20 cm
New Volume = 4000 cm³
The difference between the new volume and the initial volume will give us the amount of water that needs to be added to fill the container completely:
Amount of Water to Add = New Volume - Initial Volume
Amount of Water to Add = 4000 cm³ - 3000 cm³
Amount of Water to Add = 1000 cm³
Now, let's convert the amount of water to liters. Since 1 liter is equal to 1000 cm³:
Amount of Water to Add = 1000 cm³ ÷ 1000 (cm³/liter)
Amount of Water to Add = 1 liter
Therefore, the correct answer is:
C. 1 liter
