find the surface area of a pyramid in php

To find the surface area of a pyramid in PHP, you need to know the length of the base, the height of the pyramid, and the slant height. Once you have these measurements, you can use the following formula to calculate the surface area:

main.php
$base_length = 10; // length of the base
$height = 5; // height of the pyramid
$slant_height = 11; // slant height of the pyramid

$base_area = pow($base_length, 2);
$lateral_area = ($base_length * $slant_height) / 2;
$surface_area = $base_area + $lateral_area;

echo "The surface area of the pyramid is " . $surface_area . " square units.";

Explanation:

• We first define the length of the base, the height of the pyramid, and the slant height as variables.
• Then, we calculate the area of the base using the pow() function, which raises base_length to the power of 2 (to get its area since it's a square base).
• We calculate the lateral area by multiplying the base length by slant height, dividing that product by 2 (since we're working with a triangular shape) and finally by adding the base area to it.
• Finally, we output the surface area of the pyramid.
