The handling surcharge for items that are fragile and insurance cost for items that have a high value are two different terms that can be filled in different cells on the Excel Sheet. On the Excel sheet, the excel formula that can be used to calculate the value of the corresponding item is:
- = SUMIF (handling surcharge for fragile items: insurance cost for high_value items, criteria, [sum_range])
An Excel sheet is a spreadsheet that is used for calculating arithmetic operations, statistical calculations, and graphical analysis. In an Excel sheet, simple commands are input by using the Excel Formulas.
For the given example; the excel formula to be used is:
- = SUMIF (handling surcharge for fragile items: insurance cost for high_value items, criteria, [sum_range])
The formula is therefore being copied and pasted down in the subsequent cells below to determine the values of other corresponding items.
Therefore, we can conclude that the excel formula to be used can be seen in the format outlined above.
