find the surface area of a cube in typescript

To find the surface area of a cube in TypeScript, you would need to first find the length of one side of the cube. Once you have that value, you can use the formula for surface area, which is 6 times the square of the length of one side. Here's the code:

index.ts
function findSurfaceAreaOfCube(sideLength: number): number {
  const surfaceArea = 6 * Math.pow(sideLength, 2);
  return surfaceArea;
}

The findSurfaceAreaOfCube function takes in the length of one side of the cube as a parameter and returns the surface area of the cube as a number. The Math.pow function is used to calculate the square of the side length. This formula takes into account the fact that there are 6 faces to a cube, each with an area equal to the square of the length of one side.
