Describe how you can find the mass of the irregular shape?

To find the mass of an irregular shape, you can use the method of water displacement. Here's how you can do it:

1. Fill a container with water and record the initial volume of water in the container.

2. Carefully place the irregular shape into the container, making sure it is fully submerged in the water.

3. Measure the new volume of water in the container. The increase in volume of water is equal to the volume of the irregular shape.

4. Use the formula density = mass/volume to calculate the mass of the irregular shape. The density of water is 1 g/cm^3, so the volume of water displaced is equal to the mass of the irregular shape in grams.

5. Remove the irregular shape from the water and dry it off. Weigh the irregular shape on a scale to confirm the mass calculated using water displacement.

By using the method of water displacement, you can accurately determine the mass of an irregular shape.
