3D Modeling Using Coordinates (4): Building Composite Solids

The depth of all solids shown here = 4.5 cm. Shorter leg of the right triangle (up top) = 9.8 cm. Each side of the square (right) = 9.8 cm. The space in the middle is congruent to the prism to its left.
Construct this composite solid in the app below by plotting ordered triples at its vertices. Then use the polygon tool to build each of its faces.
