The advantage of the prismoidal formula is that it can be used to estimate the volume of solids that are combinations of other solids, which means that the correct answer is option B.
To understand why this is the case, let's first discuss what the prismoidal formula is. The prismoidal formula is a method used to estimate the volume of a prismoid, which is a three-dimensional figure with parallel bases and faces that are not parallel to the bases. It is a type of figure that includes solids such as pyramids, wedges, and frustums.
The formula takes into account the areas of the two parallel bases and the area of a section located between the bases. By using this formula, we can estimate the volume of a prismoid without having to rely on more complicated methods such as calculus.
Now, back to the question. Option A stated that the prismoidal formula can be used to determine volumes of figures that aren't prismoids. However, this is not true because the prismoidal formula specifically deals with prismoids, and would not be applicable to other types of figures.
Option C claimed that the prismoidal formula can calculate precise volumes of all prismoids. While the formula is indeed designed to estimate the volume of prismoids, it is important to note that it provides an approximation rather than a precise value. Thus, option C is not the correct answer.
Option D stated that the prismoidal formula can calculate both volume and surface area. While it is true that the prismoidal formula is primarily used to estimate the volume of a prismoid, it does not provide a method for calculating surface area. Therefore, option D is also incorrect.
In conclusion, the correct answer is option B, as the prismoidal formula is advantageous in estimating the volume of solids that are combinations of other solids.
