The equation for solving the volume of a pyramid is equal to, Volume = Bh/3
where B is the area of the base and h is height. To compute for the area of the base, we use the equation, A = aP/2 where a is apothem and P is perimeter. Substituting the known values, A = (3 mm)(5 x 4 mm) / 2 = 30 mm² Substituting the computed value to the equation for volume. V = (30 mm²)(4.1 mm) / 3 = 41 mm³ Thus, the answer is letter A.
True - since the outlier is way off it will cause your average to mess up which is why we test multiple times to make sure we are more accurate with our numbers
