Problem Statement
We are given a solid right pyramid. This pyramid has a regular hexagonal base, and the area of this base is 7.4 square units. The pyramid's height, which is the perpendicular distance from the apex (the top point) to the base, is 6 units. Our objective is to determine the volume of this pyramid. This problem combines the concepts of two-dimensional geometry (the hexagonal base) and three-dimensional geometry (the pyramid's volume). To solve this, we need to recall the formula for the volume of a pyramid and apply it correctly. Understanding the properties of a hexagon, such as its area calculation, is also crucial. The challenge lies in connecting these geometric concepts and performing the calculation accurately. This problem is not just about numbers; it's about spatial reasoning and the application of mathematical principles.

The application of the volume formula will be the cornerstone of our solution, and we will ensure that you understand how to use it effectively. Let's proceed with the solution, step by step, and uncover the volume of this fascinating hexagonal pyramid.
Formula for the Volume of a Pyramid
The volume V of any pyramid is given by the formula:
V = (1/3) * B * h
where B is the area of the base and h is the height of the pyramid. This formula is a cornerstone of solid geometry and applies to all types of pyramids, regardless of the shape of their base. Understanding this formula is essential for calculating the volume of any pyramid, whether it has a triangular, square, pentagonal, hexagonal, or any other polygonal base. The formula reflects the fundamental relationship between the base area, height, and volume of a pyramid. It tells us that the volume is directly proportional to both the base area and the height. This means that if we double the base area, we double the volume, and if we double the height, we also double the volume. This intuitive relationship makes the formula easy to remember and apply. The formula's simplicity is deceptive, as it encapsulates a profound geometric principle. To effectively use this formula, we must ensure that we have the correct values for both the base area and the height, and that we use consistent units of measurement. The base area B represents the two-dimensional space enclosed by the base of the pyramid, while the height h represents the perpendicular distance from the apex of the pyramid to the plane of the base. Understanding these definitions is crucial for accurately identifying and using these values in the formula. The formula for the volume of a pyramid is a powerful tool in the world of geometry, and mastering it allows us to solve a wide range of problems related to three-dimensional shapes. In the next section, we will apply this formula to our specific problem, where we are given the base area and the height of a hexagonal pyramid. Let's see how this formula works in practice and calculate the volume of our pyramid.
Applying the Formula
In our problem, we are given that the base area B is 7.4 units² and the height h is 6 units. We can directly substitute these values into the formula for the volume of a pyramid:
V = (1/3) * B * h V = (1/3) * 7.4 * 6
Now, we perform the calculation:
V = (1/3) * 44.4 V = 14.8
Therefore, the volume of the pyramid is 14.8 units³. This calculation demonstrates the straightforward application of the volume formula. We simply plug in the given values for the base area and the height, and then perform the arithmetic to arrive at the volume. The key to success in this step is to ensure that we are using the correct units and that we perform the calculations accurately. Mistakes in arithmetic can lead to an incorrect answer, so it's important to double-check our work. The process of substitution is a fundamental skill in mathematics, and this problem provides a clear example of how to apply it in a geometric context. We take the given information, identify the relevant variables in the formula, and replace those variables with their corresponding values. This process allows us to translate a general formula into a specific solution for our problem. The result of our calculation, 14.8 units³, represents the amount of three-dimensional space enclosed by the pyramid. This volume is a measure of the pyramid's capacity, and it is expressed in cubic units because it is a three-dimensional quantity. Understanding the units of measurement is crucial for interpreting the result correctly. In this case, the units are units³, which indicates that we are measuring a volume. With the volume calculated, we have successfully solved the problem. Let's move on to the next section to review our answer and ensure that it makes sense in the context of the problem.
Solution
Based on our calculations, the volume of the pyramid is 14.8 units³. This corresponds to option B in the given choices. The solution process involved applying the formula for the volume of a pyramid, which is V = (1/3) * B * h, where B is the area of the base and h is the height. We substituted the given values, B = 7.4 units² and h = 6 units, into the formula and performed the calculation to arrive at the answer. The final answer, 14.8 units³, represents the amount of space enclosed within the pyramid. This value is a concrete measure of the pyramid's size and provides a clear understanding of its three-dimensional extent. The correct selection of option B confirms that our calculations and application of the formula were accurate. This process highlights the importance of understanding the underlying geometric principles and applying them correctly to solve problems. The solution not only provides a numerical answer but also reinforces our understanding of the relationship between the base area, height, and volume of a pyramid. This knowledge can be applied to a variety of similar problems, making it a valuable tool in the study of geometry. The accuracy of the solution depends on the correct application of the formula and the careful execution of the arithmetic. By following a step-by-step approach, we can minimize the risk of errors and ensure that we arrive at the correct answer.
