Comparing Volumes of Objects

In order to compare the volumes of different objects, we need to convert the given measurements to a consistent unit. Let's convert the given volumes to cubic meters, which is the standard unit for volume.

1) Comparing the volumes of the objects:

- 0.5 m³ - 5000 ml - 500 dm³

To compare these volumes, we need to convert them all to cubic meters. Here are the conversions:

- 0.5 m³ = 0.5 m³ (already in cubic meters) - 5000 ml = 5 liters = 0.005 m³ (1 liter is equal to 0.001 cubic meters) - 500 dm³ = 500 liters = 0.5 m³ (1 liter is equal to 0.001 cubic meters)

Now, let's compare the volumes:

- 0.5 m³ is equal to 0.5 m³. - 5000 ml is equal to 0.005 m³. - 500 dm³ is equal to 0.5 m³.

Therefore, among the given volumes, the volumes of the objects in 0.5 m³ and 500 dm³ are equal. [[1]]

Drawing a Graduated Cylinder Scale

To draw a graduated cylinder scale with a division of 50 ml, we can follow these steps:

1. Draw a vertical line to represent the graduated cylinder. 2. Mark the starting point of the scale at the bottom of the line. 3. Divide the line into equal segments, each representing 50 ml. 4. Label each segment with the corresponding volume, starting from the bottom.

Here is an example of a graduated cylinder scale with a division of 50 ml:

   |____________________
   |                    |
   |        50 ml       |

   |                    |
   |       100 ml       |
   |____________________|
   |                    |
   |       150 ml       |
   |____________________|
   |                    |
   |       200 ml       |
   |____________________|
   |                    |
   |       250 ml       |
   |____________________|
   |                    |
   |       300 ml       |
   |____________________|
   |                    |
   |       350 ml       |
   |____________________|
   |                    |
   |       400 ml       |
   |____________________|
   |                    |
   |       450 ml       |
   |____________________|
   |                    |
   |       500 ml       |
   |____________________|

Please note that the scale can be extended further based on the required range of volumes.
