Formula to multiply units of section sizes

**Juleskor** · 04-22-2013, 09:01 PM

Hi,
I have a spreadsheet where I have unit sizes in place based on page sizes. eg. 48 pages, 24 pages, 12 pages, 8 pages located in cells A2, B2, C2 and D2. I want to be able to sum the total of these columns based on the number of units in each column. So if 48 pages has 1 unit, 24 pages has 0 units, 12 pages has 0 units and 8 pages has 2 units the sum would be 48x1 +24x0 + 12x0 + 8x2 = 64.
I have worked this out for each row as =SUM(A3*A2,B3*B2,C3*C2,D3*D2) but there are 80 rows and I was wondering if there was a simpler method. I have embedded an image to help illustrate the spreadsheet.

Attach a sample workbook. Make sure there is just enough data to make it clear what is needed. Include BEFORE/AFTER sheets if needed to show the process you're trying to complete or automate. Remember to desensitize the data.

Click on GO ADVANCED and use the paperclip icon to open the upload window.

Thanks Davesexcel

I have been working in Google Docs but have saved this as an XLSX document and attached it taking out the sensitive data.

Try it like this:

=SUM(A3*A$2,B3*B$2,C3*C$2,D3*D$2)
copy down as far as needed

If you want elegant way then try this:

=SUMPRODUCT(A$2:D$2,A3:D3)
copy down as far as needed

Thanks Teethless mama,
When you say copy down as far as needed, I would need to copy the formula into each cell in column E? and change the A3 B3 C3 D3 to A4 B4 C4 D4 and so on?
