Carpentry Problem of the Day

I need to build a platform for a dishwasher.

Image Not to Scale created with SketchUp for free.

It needs to be 17 7/8" x 22 1/2" x 2".

I have one 8' 2x4.

I'm going to cut four pieces out the 2x4 to make the sides of the platform.

How long does each piece need to be?

Extra credit:
Do I need to add additional lumber to make the platform 2" high?

Update, here's the platform:

    Is this for real? Just measure the 2x4 and cut it. Assuming you are laying the 2x4 flat (though that will make the pieces hard to connect) cut 2 pieces 22 1/2 long and cut 2 pieces 10 7/8 long. Fit the short pieces inside the long ones and connect them. As for the height you will have to add 1/2" of height to the 2x4 as it is actually only 1 1/2" thick. That will be tricky because half inch boards are hard to find although some places like Home Depot have them for drawer making. You can use half inch plywood but then you have to cut it. Now, what do I get as a reward for answering your problem? (A case of Mackeson Triple x Stout would be great!)

    ps-sometimes using an old fashioned piece of graph paper is a really easy way of planing can lay it out to scale and see exactly how it is going to work,,,none of this fancy schmancy cad stuff..

  2. Thanks Mark. It's for real. I had already figured it out, but thought it would be fun to ask readers about it and document the answer.

    One thing you don't mention is that the 2x4 is actually only 3 1/2 inches wide.

    Each side is going to be 3 1/2" wide so you subtract that from 17 7/8.

    17 7/8 - ( 2 x 3 1/2) = 10 7/8.

    Easy for you to say, but to someone who doesn't work with carpentry that much it's confusing until you get the actual wood in front of you.

    As for the extra 1/2 inch top, I have some 1/2 inch wood flooring I can use...
