Prisms practice seventh grade answers
1. A prism is a polyhedron with two parallel and congruent polygonal bases connected by rectangular or parallelogram lateral faces.
2. The volume of a prism is given by the formula V = Bh, where B is the area of the base and h is the height of the prism.
3. The surface area of a prism is given by the formula SA = 2B + Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the prism.
4. The bases of a prism can be any polygon, such as a triangle, square, pentagon, etc.
5. The lateral faces of a prism are always rectangles or parallelograms.
6. The number of lateral faces in a prism depends on the number of sides in the base polygon.
7. A right prism is a prism where the lateral faces are perpendicular to the bases.
8. An oblique prism is a prism where the lateral faces are not perpendicular to the bases.
9. The cross section of a prism is a polygon that is parallel and congruent to the bases.
10. Some real-life examples of prisms include buildings, boxes, and cylinders.
