Chapter: Geometry And Measurement
Solids are three-dimensional figures with length, width, and height. They occupy space (volume) and have outer surfaces that can be measured (surface area). Solids can be regular (all faces congruent) or irregular, and many real-world objects are modeled using combinations of common solids such as prisms, pyramids, cylinders, cones, and spheres. Understanding their properties is essential in construction, packaging, engineering, and daily problem-solving.
1. Calculates and interprets surface area and volume of solids (e.g., prisms, pyramids, cylinders, spheres) and composite solids, including in real-world situations
Prisms A prism has two congruent, parallel polygonal bases and rectangular faces connecting them.
- Volume: V = Base area × height
- Surface area: SA = 2 × Base area + Perimeter of base × height
