A prism is a geometric solid that has two parallel and congruent (equal) bases connected by lateral faces that are parallelograms (usually rectangles). ✏️ Characteristics of prisms Equal and parallel bases – The two bases are identical polygons (such as triangles, squares, pentagons…). Lateral faces – These are parallelograms, generally rectangles in right prisms. Edges – Line segments that connect the vertices of the bases or that form the sides of the bases and lateral faces. Vertices – Points where three edges meet. Height (h) – Distance between the bases (perpendicular to them). 📦 Elements of a prism Bases: the two parallel and congruent faces. Lateral faces: the other faces (number depends on the polygon of the base). Edges: the lines that connect the vertices. Vertices: the points where the edges meet. Height (or h): perpendicular distance between the two bases. 🧱 Types of prisms (according to the base) Prism Type Base Visual Example (imagine) Triangular prism Triangle A camping tent Quadrangular prism Square or rectangle A shoebox Pentagonal prism Pentagon A jewel with 5 sides Hexagonal prism Hexagon A thick screw ✅ Tip to identify a prism: See if it has two identical bases (top and bottom). See if the other faces are parallelograms. A parallelepiped, for example, is a prism whose base is a rectangle! Summary about prism volume To calculate the volume of the prism, simply find the area of ​​the base and multiply by the height. The formula for the volume of a prism is: V = Ab x h V: volume Ab: area of ​​the base h: height of the prism A prism is a geometric solid with two parallel and congruent bases. The base of the prism can have different shapes: triangle, square, rectangle, pentagon, hexagon, among others. The first step to calculating the volume of the prism is to identify the shape of its base. Cavalieri's principle allows comparing volumes of solids with the same height and equivalent cross-sections. ---- ➡️This content was produced by the Municipality of Anápolis, SEMED - Municipal Department of Education, CEADI – Municipal Center for Distance Learning of Anápolis. 🤝Objective: To connect students, teachers and families in building a public, innovative and quality education. 📚 For more lessons, tips, and learning paths, subscribe to the channel, activate the bell 🔔 and follow our content! ✨ Also visit our website: 👍https://sites.google.com/edu.anapolis... 🎯 Keywords: free video lessons, school reinforcement, elementary education, BNCC (National Common Core Curriculum), innovative education, hybrid teaching, teacher training, quality public education, Continuing Education.
