Answer 1

Calculating the Volume of Water Needed to Fill a Container

To determine the volume of water needed to fill a container, we need to know the total volume of the container and the current amount of water in it. In this case, we are given that 1/5 of the container is not filled with water and we need to calculate the volume of water required to fill the container completely.

Let's assume that the total volume of the container is represented by V and the current volume of water in the container is represented by W.

To find the volume of water needed to fill the container completely, we can use the following formula:

Volume of water needed = Total volume of the container - Current volume of water in the container

In this case, since 1/5 of the container is not filled with water, the current volume of water in the container can be calculated as:

Current volume of water in the container = (4/5) * V

Substituting this value into the formula, we get:

Volume of water needed = V - (4/5) * V

Simplifying the equation, we have:

Volume of water needed = (1/5) * V

Therefore, to fill the container completely, Ahmad needs to add 1/5 of the total volume of water that the container can hold.

Please note that the specific volume of water needed depends on the total volume of the container, which is not provided in the question.
