Please help!

Thanks for your site - it's great! I'm trying to measure the cubic feet I'll need to build a strange-looking structure. It is a concrete shield for cameras for use in hurricanes or other extreme weather. It is a modified pyramid with a 4' x 4' square rectangular top, 7' from top to bottom, 8' wide at the base, with all four walls and the rectangular top each 6" thick. On its side about 6' up are two ports for the cameras that at 8" high, 8" wide and 6" deep. The 8' x 8' base is also 6" thick. Based on these measurements, can you tell me how many cubic feet of concrete I need for this structure? I can't begin to tell you how grateful I will be if you can help!

Why did the vector cross the road?
It wanted to be normal.
