A family of Microsoft word processing software products for creating web, email, and print documents.
An easy way to do this is to select a Business Card label layout (such as Avery 3612) from Mailings | Create | Labels | Options. This is also available under Microsoft (as vendor) as the last one of the Business Card options (Horizontal Card 2" x 3.5"). Click New Document in the main Labels dialog to get a sheet of them.
These layouts do give you ten cards with margins. If you need to make the cells fill the whole page, you can set margins to 0" and change the cell height and width accordingly, but you won't likely be able to print to the edge.
If you have Publisher available, it allows you to design your entry form once and then print it 10-up.
