Let 's x the length of the pyramid:
V=x²*h/3
V=1024 and h=12
So x²*12/3=1024
==>x²=1024*3/12
==>x²=256
==>x²=16²
==> x=16 for (x=-16 must be exclude <0)

Answer:
Find a flat screen monitor that's still working.
Unscrew the screws that secure the outer casing of the monitor. If there are any locks that snap in, don't be afraid to break them.
Plan where you wish to place screws in the top and bottom faces of monitor's frame. Depending on the size of your monitor, you might wish to have the screws closer together to help distribute the monitor's weight evenly. Drill the holes carefully with your dremmel tool.
Create a frame for the top and bottom of your monitor from the three pieces of L-channel. Alter the 90-degree angle of the one of the metal L-channels to a 70-degree angle or so, which will allow the monitor to be at a slight angle without tipping over. Mark and drill holes in the L-channel so that will match up with those you have drilled in the monitor. For the third L-channel, drill holes that will form the base.
Measure the screws and shorten them if necessary. The screws should be long enough to fit through the Plexiglas, the monitor, the frame and a little more. You can shorten the screws to the length you like with the dremmel tool.
Cut the Plexiglas so one piece will fit over your monitor. Cut a second piece of Plexiglas that will be the base of the computer monitor you are building. Mark where to drill the holes so they will match up with the ones you have drilled in the monitor. Drill holes along the bottom of the Plexiglas that will match up with those in the third L-channel.
Insert the screws, and secure the large piece of Plexiglas to the front of the monitor. Secure the second piece of Plexiglas to the third piece of L-channel to form the base.
Items you will need
Screws
L-channels (metal bars that have a 90-degree angle)
Plexiglas (large enough to cover your monitor)
Dremmel tool
Hammer
Safety glasses
Dust mask
