Chapter 27.2
Surface area and volume of pyramids
What You'll Learn
Calculate the surface area of pyramids by finding areas of triangular faces and the base
Apply the Pythagorean theorem to find slanted side heights of pyramid faces
Use the volume formula for pyramids: one-third times base area times height
Distinguish between pyramid height and slanted side height in calculations
Work with both square and rectangular pyramid bases in problems
What You'll Practice
1
Finding missing slanted sides using the Pythagorean theorem
2
Calculating surface area of square and rectangular pyramids
3
Computing pyramid volume using base area and height
4
Converting between units (millimeters to centimeters) before solving
Why This Matters
Understanding pyramid surface area and volume is essential for solving real-world problems in architecture, engineering, and design. These skills build your spatial reasoning and prepare you for advanced geometry, trigonometry, and calculus applications involving three-dimensional shapes.
