Example: Find the volume of a square pyramid with a height of 12 cm and base edges of 4 cm. Solution: Use the formula for the volume of a pyramid: First, find the area of the base, which is 4cm x 4cm = 16cm² Next, plug values into the formula. V = 1/3 (16cm²) 12cm V=(192cm³) 12 cm し 4cm 4cm V = 64 cm³ Lesson 17 Review: Find the volume of each pyramid with the given values. 1. A four-sided pyramid with base edge of 5 ft and h = 4 ft. 2. A four-sided pyramid with base edge of 10 ft and h = 7 ft. 3. A four-sided pyramid with base edge of 8 yds and h = 9 yds. 4. A four-sided pyramid with base edge of 20 ft and h = 15 ft. 5. A four-sided pyramid with base edge of 11 in and h = 20 in.
