Can I attach these legs to plywood?

It should work. Over time, the plywood may sag. You want to run a strip or two on the underside in a vertical position. Sort of like building a bridge or a beam it will add lots of stiffness. You can even cut the strips from the plywood if you are not using the full width.

The edges can also be covered with an iron on edging to make it look finished. A nice piece of 3/4" plywood will cost from $45 for the more common grades like birch, to $100 for cherry and other nicer grades. Ed snipped-for-privacy@snet.net

go for it

No problem. Use 3/4" long screws in a piece of 3/4" plywood.

Then cheat. Two drawer file cabinets are the right height and are available at barewood furniture places and your local lumber provider can cut the plywood to fit the top 24 inches by 72 is a big desk with storage. Some Screws from the cabinet into the plywood to hold it in place (not really needed, Double backed tape works just as well) Finish it your way. One all wood computer desk

Something else to consider, take 2 two drawer file cabinets and an old door. I know it sounds silly, but it works. Neighbor found a solid door, and he is using it for his sons "desk" and that boy abuses everything. He has had it for a few years now good to go
