I do not understand how to measure the volume of a star shape medallion. I think I would multiply all the stars on the medallion. Thanks for your help.
To measure the volume of a star-shaped medallion, you cannot simply multiply the number of stars on the medallion. The volume of an object is a measure of the space it occupies, and for irregular shapes like star-shaped medallions, more advanced techniques are required.
Here's a step-by-step explanation of how you can estimate the volume of a star-shaped medallion using the water displacement method:
1. Fill a container with enough water so that when you submerge the medallion, it will be completely covered.
2. Carefully place the medallion into the container, ensuring it is fully submerged. Take note of the initial water level.
3. As the medallion is submerged, it displaces an amount of water equal to its volume. The difference in water level before and after the medallion is submerged represents this displacement.
4. Take the medallion out of the container and measure the change in water level accurately, either by using a measuring cup or by marking the water level on the container and pouring it into a measuring cylinder.
5. The change in water level represents the volume of the medallion. This is because the amount of water displaced is equal to the volume of the medallion.
By following these steps, you can estimate the volume of the star-shaped medallion using the water displacement method. Keep in mind that this method provides an approximation, as it assumes the medallion is completely solid without any hollow parts.
