    Answer: 109.5 in³

    Step-by-step explanation:

    1. The perimeter of the square base is given to be 18.3 inches. Since the base is a square, it can be divided by 4 to find the length of each side. This gives us 4.575 inches.

    2. The formula for the volume of a pyramid is 1/3Bh. We can substitute the square of 4.575, which is 20.930625. That is substituted into the equation, making 1/3(20.930625)h inches. Additionally, the height is given as 15.7 inches, meaning we can substitute 15.7 for h. This gives us the final formula of V=1/3(20.930625)(15.7)

    3. Use order of operations to solve the problem. Bh (20.930625)(15.7) is 328.6108125. Dividing this value by 3 gives 109.5369375, which rounds to 109.5 in³, which is the final answer.
