find the surface area of a rectangular prism in javascript

To find the surface area of a rectangular prism in JavaScript, you can create a function that takes in the length, width, and height of the rectangular prism as parameters. The formula for the surface area of a rectangular prism is:

SA = 2lw + 2lh + 2wh

where l is length, w is width, and h is height.

Here's an example function that calculates the surface area of a rectangular prism:

index.tsx
function getSurfaceArea(length, width, height) {
  const sa = 2 * (length * width + length * height + width * height);
  return sa;
}

You can call this function with the length, width, and height of a rectangular prism to get its surface area:

index.tsx
const length = 5;
const width = 4;
const height = 3;

const sa = getSurfaceArea(length, width, height);

console.log(sa); // Output: 94

In this example, the rectangular prism has a length of 5, a width of 4, and a height of 3. The getSurfaceArea() function calculates its surface area using the formula 2lw + 2lh + 2wh, which is equal to 2*5*4 + 2*5*3 + 2*4*3 = 94. The surface area of the rectangular prism is 94.
