The length of an object was measured 3 times with the following results: 6.145 cm, 6.12 cm, 6.2 cm.

1. Determine the average length of the object in cm: ____
2. If the above values are the length, width, and height of a rectangular cuboid, calculate the volume of the cuboid in cubic cm: ____
3. Convert this volume to cubic meters: ____

Answer :

Final answer:

The average length of the object is 6.155 cm. The volume of the cuboid is 239.65744 cm³. The volume in cubic meters is 0.00023965744 m³.

Explanation:

To find the average length of the object, you need to add up the three measurements and divide the sum by 3. In this case, the sum of the measurements is 6.145 cm + 6.12 cm + 6.2 cm = 18.465 cm. Dividing this by 3, you get an average length of 6.155 cm.

To calculate the volume of a rectangular cuboid, you simply multiply the length, width, and height. Assuming the values given correspond to length, width, and height respectively, the volume would be 6.145 cm * 6.12 cm * 6.2 cm = 239.65744 cm³.

To convert the volume from cm³ to m³, you need to use the fact that 1 m = 100 cm. So, to convert from cm³ to m³, you divide the volume in cm³ by (100 cm)^3 = 1,000,000 cm³. Therefore, the volume in cubic meters is 239.65744 cm³ / 1,000,000 = 0.00023965744 m³.
