How is the volume of a rectangular prism calculated?

Volume = length * height
Volume = length * width * height
Volume = width * height
Volume = 2 * length * height

The correct answer is: Volume = length * width * height

The volume of a rectangular prism is calculated using the formula that includes all three dimensions: length, width, and height. This is because volume measures the amount of three-dimensional space an object occupies, and in the case of a rectangular prism, this space is defined by multiplying these three measurements together. When you multiply the length by the width, you get the area of the base of the prism. Then, by multiplying this base area by the height, you extend that area through the height of the prism, effectively filling the volume. This comprehensive approach ensures that all dimensions contribute to the total space contained within the prism. Thus, the formula that expresses this relationship accurately is length multiplied by width, multiplied by height.
