Study Notes
Surface Area Concepts
- Slant height (h) is included in the formula SA = (1/2) b² (h) for calculating surface area.
- Surface area is defined as the total area of all faces of a three-dimensional figure.
Surface Area Formulas
- The correct formula for the surface area of a cube is not SA = 2 lw + 2wh + 2lh; this formula is incorrect.
- It is false that the top and bottom faces of a cube are specifically defined without additional context or clarification.
- The formula SA = 4 (1/2 bh) + b² is specifically used to find the surface area of a square pyramid, which incorporates both the triangular faces and the base.
