![]() It works for right prisms and oblique prisms. The formula for finding the volume of a prism is: V Sh V S h where V is the volume, S is the area of the base, and h is the height of the prism. You should always use cubic units when youre calculating volume because youre working with three dimensional objects. If you had an oblique prism, as long as you know the height, and you can calculate its base area, that will be the same. As we said, a pyramid takes up 1/3 of the volume of a prism when their bases and height are equal. Step 2: Find the volume of the prism using the formula V B × H where V, B, and H are the volume. So this way, this formula volume, equals base area times height, can be applied to any kind of prism. Volume of a prism (area of base) height Now, let's consider the volume of a pyramid. Step 1: First write the given dimensions of the prism. If you had, let's say, a regular hexagon, you're going to use apothem times side length times the number of sides, divided by two. Finding the volume of a rectangular prism isnt so bad, especially if you already know the length, width, and height. And that's how you would calculate your base area. So if this was a trapezoid, then you would substitute in B1 plus B2 times H, all divided by two. To use the calculator: Enter the area of the base of the prism. How to Use the Prism Volume Calculator Our prism volume calculator is designed to make it easy for you to find the volume of any prism. So whatever your base area is, and I guess I should write base area, you're going to substitute in that formula. The formula for finding the volume of a prism is: V Sh V S h where V is the volume, S is the area of the base, and h is the height of the prism. The volume is equal to the product of the ar. This formula will work no matter what kind of prism you have. This geometry video tutorial explains how to calculate the volume of a triangular prism using a simple formula. ![]() The right hand picture illustrates the same formula. ![]() The formula, in general, is the area of the base (the red triangle in the picture on the left) times the height, h. Both of the pictures of the Triangular prisms below illustrate the same formula. So the reason why this formula is useful is because you might have a triangular prism, a trapezoidal prism, a hexagonal prism. The calculator performs calculations in a right regular prism. The volume of a triangular prism can be found by multiplying the base times the height. Where capital B is your base area and capital H is the height of the prism. So when I write my volume formula, I'm going to say the volume, "V" of this prism, is equal to its base area times its capital H, its height. So I'm going to shade in our bottom base here, and I'm going to label this as capital B. If you want to calculate the volume of any prism, there is only two things that you need to know: One, what is the height of that prism, and two what is the area of one of your bases.
