stiks02 [169]

Answer:

Sum: 18

Conversion to inches: 7.0866

Step-by-step explanation:

Not exactly sure what you are trying to ask here... But I'll do my best?

1.   If you are trying to add each measurement together, you start by writing out:   6 + 5 + 4 + 3. Now you can break it down into smaller parts to be easier.

6 + 5 = 11.  11 + 4 = 15. 15 + 3 = 18.

So the sum of the measurements is 18!

_________________

2. If you are trying to convert this measurement into inches, you could follow these directions:

Since one inch is equal to about 2.54 centimeters, you would need to divide the sum of the values by 2.54.

So 18 / 2.54 is roughly equal to: 7.0866.
