What is the formula used to calculate the area of a square pyramid?

• A. ah/3
• B. ah/2
• C. a^2 h/3
• D. a^2 h

Answer: (C)

The formula for calculating the volume of a square pyramid is derived from its geometric properties. A square pyramid consists of a square base and triangular faces that meet at a point (the apex). To find the volume, you multiply the area of the base by the height of the pyramid and then divide by three, which accounts for the three-dimensional shape tapering to a point at the top. For a square pyramid, the area of the base (which is a square) is represented as \( a^2 \), where \( a \) is the length of a side of the base. The height of the pyramid, which is a perpendicular line from the base to the apex, is denoted as \( h \). The final formula for the volume of the square pyramid is thus \( \frac{1}{3} \times \text{(Area of base)} \times h \), or specifically \( \frac{a^2 h}{3} \). This relationship clearly shows why the volume is one-third the product of the squared base area and the height. Therefore, the choice that represents this formula accurately is \( a^2 h/3 \).

For a square pyramid, the area of the base (which is a square) is represented as ( a^2 ), where ( a ) is the length of a side of the base. The height of the pyramid, which is a perpendicular line from the base to the apex, is denoted as ( h ).

The final formula for the volume of the square pyramid is thus ( \frac{1}{3} \times \text{(Area of base)} \times h ), or specifically ( \frac{a^2 h}{3} ). This relationship clearly shows why the volume is one-third the product of the squared base area and the height. Therefore, the choice that represents this formula accurately is ( a^2 h/3 ).
