A pentagonal heptahedron. A heptahedron is a solid figure with seven faces, and a pentagon is a five-sided plane figure.
decahedron
A heptahedron. It could be a pyramid with a hexagonal base, or a pentagonal prism. There are other possibilities but no obvious names spring to mind.
Decagon, if a plane figure or decahedron, if a solid.
A seven or 7 sided polygon shape is called a Heptagon(hep-ta-gone).
A polyhedron is a solid figure with many plane faces, usually greater than six. A polyhedron that has 7 faces is called a heptahedron.
true
A solid has a depth, a plane figure does not.
Yes and no. Yes = plane figure No = solid figure.
A solid figure.
2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
No it is not a plane but it is a solidfigure
