Names of different 3D figures( polyhedron and Not polyhedron)? | A= Cone(NP), Cube (P), Cylinder (NP), Rectangular Pyramid (P), Rectangular Prisms (P) |

How to find the Faces, Edges, and Vertices of 3D figures? | A= To find the faces, you can count the 2D shapes that make up the whole 3D shape. To count the edges, count the lines that make up the whole thing. To find the vertices, count the points where 3 or more edges meet. |

What is the formula for volume of a rectangular prism? | The formula is: length * width * height |

What is the formula to find the voluma of a triangular prism? | A= Triangular prism= 1/2 * length * width * height |

What is a prism? | A= A prism is a solid object that has 2 identical ends and all flat sides. The cross section is the same all along its length. The shape of the ends give the prism its name. |

What is a cylinder? | A= Cylinder= a solid object with two identical flat ends that are circular or elliptical and one curved side. It has the same cross-section from one end to the other. |

What is the formula to find the volume of a cylinder? | A= pi (r^2h) |

What is a square pyramid? | A= A solid figure with a base that is a square and four faces that are triangles meeting at a point. |

What is the formula to find a square pyramid? | A= v= 1/3b^2h |

What is a cone? | A= A solid or hollow object that tapers or begins from a circular or roughly circular base to a point. |

What is the formula to find the volume of a cone? | A= (1/3)*pi* radius^2* height |

What are the units for volume? | A= units cubed (units^3) |
