Final answer:
The volume of the pyramid with a square base area of 6.8 m² and height of 8.6 m is 19.5 m³ when rounded to the nearest tenth.
Step-by-step explanation:
To find the volume of a pyramid with a square base, where the area of the base is 6.8 m² and the height of the pyramid is 8.6 m, we use the formula for the volume of a pyramid, which is V = ⅓ × (base area) × height. Plugging in our values, we get:
V = ⅓ × 6.8 m² × 8.6 m
To calculate, simply multiply the values and divide by 3:
V = ±(6.8 m² × 8.6 m) = ±(58.48 m³) = 19.4933 m³
When rounded to the nearest tenth of a cubic meter, the volume is 19.5 m³.
