How i went about creating my wedges was first sizing each cube on the X axis to stretch each cube out in Object Mode. Second i switched over to Edit Mode where i then grabbed the top two vertices on the front side of my rectangles. After i made the first wedge i decided to make a smaller and larger version. I did the same process except when i made the second cube i sized it bigger before i stretched it for the large wedge, and i made a third block and sized it down before i stretched it for the smaller wedge. I also scaled each wedge a bit larger based off the size. You can see in the object frame at the top right i have renamed all my wedges to appropriate names. Thanks for checking it out! Oh future reference there is a duplicate selected button i found that will actually copy the selected object in the 3d window frame. I realized after i created these the longer way
