calculateVolumeTriangularPrism()

Step 1: Understand the Problem

Before we start coding, we need to understand the problem. We want to calculate the volume of a triangular prism. The volume of a triangular prism is given by the formula base_area * height. And triangular is given by the formula 0.5 * base * height. So, we will accept three inputs: base, height and prism height. We then calculate the base_area from base and height and multiply it by prism height.

Step 2: Starting our function

Starting off, we need to define a function. We'll call it calculateVolumeTriangularPrism. This function will accept three parameters: base, height (height) and prism height (prismHeight).

function calculateVolumeTriangularPrism(base, height, prismHeight) {
// Code goes here 
}

Step 3: Calculating the triangular base area

Inside our function, the first step is to calculate the area of the triangular base. As explained earlier, that's computed by 0.5 * base * height. We'll store this result in a variable: base_area.

function calculateVolumeTriangularPrism(base, height, prismHeight) {
    var base_area = 0.5 * base * height;
}

Step 4: Calculating the volume

Once we have the base_area, we can calculate the volume of the prism by multiplying base_area with prismHeight. We'll store this in a variable called volume.

function calculateVolumeTriangularPrism(base, height, prismHeight) {
    var base_area = 0.5 * base * height;
    var volume = base_area * prismHeight;
}

Step 5: Returning the result

Finally, we need to make our function return the volume. We simply add a return statement at the end of our function with the variable volume.

function calculateVolumeTriangularPrism(base, height, prismHeight) {
    var base_area = 0.5 * base * height;
    var volume = base_area * prismHeight;
    return volume;
}

This is the complete implementation of our function. Now the function calculateVolumeTriangularPrism is ready to calculate the volume of a triangular prism when provided with the base, height and prism height.
