    The correct answer is A. 22 inches ³

    Step-by-step explanation:

    Let's recall that the formula of the volume of a triangular pyramid:

    Volume = 1/3 * Area of the base * height

    Replacing with the values we have:

    Volume = 1/3 * 11 inches² * 6 inches

    Volume = 66/3

    Volume = 22 inches ³

    The correct answer is A. 22 inches ³
