Final answer:
To find the volume of a pyramid with a square base, multiply the area of the base by the height and divide by 3. The volume is approximately 5.7 cubic inches.
Step-by-step explanation:
To find the volume of a pyramid with a square base, you need to multiply the area of the base by the height of the pyramid and divide the result by 3. The formula for finding the volume of a pyramid is V = (1/3) × base area × height. Given that the area of the base is 5.7 in² and the height is 2.9 in, we can calculate the volume:
V = (1/3) × 5.7 in² × 2.9 in
V ≈ 5.7 in³
Therefore, the volume of the pyramid is approximately 5.7 cubic inches when rounded to the nearest tenth.
