Octagonal prism.
Since it has 10 faces, it must be a decahedron.

An octagonal prism has 24 edges.An octagonal prism has 16 vertices.An octagonal prism has 10 faces, two octagons on the "ends" and eight quadrilaterals (often rectangles) on the "sides". The correct number is 24
You could make 5 rectangles with 10 squares
For all polyhedra: vertices + faces = edges + 2 The given fact is: edges = vertices + 10 → vertices + faces = vertices + 10 + 2 → faces = 12
All rectangles which have sides in the ratio 10:15 would be similar. This would include 2 x 3, 4 x 6, 100 x 150, etc. Note that similarity in rectangles is very simple, since all interior angles are by definition right angles.
12 faces, 30 edges and 20 vertices. It has 2 decagons plus 10 rectangles between them giving 12 faces It has 2 x 10 vertices on each decagon giving 20 vertices It has 10 edges round each decagon plus another 10 joining the vertices of one decagon to the other decagon's vertices giving 2x10+10 = 30 vertices
10 faces 10 faces
7 horizontal lines and 10 vertical lines how many rectangles?
