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
