Question
**Example**

5. Kamilah is making a model of the Food Guide Pyramid for a class project. Find the volume of the square pyramid.

\[ V = \frac{1}{3} B h \]

\[ V = \frac{1}{3} (12 \times 12) 12 \]

\[ V = \frac{1}{3} 144 \times 12 \]

\[ V = 576 \]

The volume is 576 cubic inches.

**Guided Practice**

*Find the volume of each pyramid. Round to the nearest tenth if necessary.* (Examples 1 and 2)

1. A pyramid with a square base (23 yd by 23 yd) and height (25 yd).

2. A triangular pyramid with base length (2.2 cm), base height (2.9 cm), and slant height (1.8 cm).

*Find the height of each pyramid.* (Examples 3 and 4)

3. A square pyramid with volume (1,024 cm³) and base edge (16 cm).

4. A triangular pyramid with volume (48 in³), base edge (9 in), and base height (4 in).

5. The Transamerica Pyramid is a skyscraper in San Francisco. The rectangular base has a length of 175 feet and a width of 120 feet. The height is 853 feet. Find the volume of the building. (Example 5)

6. **Building on the Essential Question:** When you are finding the volume of a pyramid, why is it important to know the shape of the base of the pyramid?

**Rate Yourself!**

*How well do you understand the volume of pyramids? Circle the image that applies.*
