Solid 3D figures are called polyhedrons. To figure out what a polyhedron with a specific number of sides is, you take the Greek prefix for the number of sides, and add the suffix "-hedron" at the end: tetra=4, so it would be called a tetrahedron if it has 4 sides. penta=5, so pentahedron. hexa=6, hepta=7, octa=8, ennea=9, deca=10 So your figure would be called a decahedron.
