Formula Explanation

Area of a Triangle

The area of ANY triangle with base b and height h. This formula applies to any triangle (right, acute, or obtuse) when the height is measured perpendicular to the base. The triangle does NOT need to be a right triangle.

Volume of a Square Pyramid

The volume of a square pyramid with base b and height h.

Formulas

  • Area: A = \(b h \over 2\)

  • Volume: V = b2 \(h \over 3\)
