find the volume of a rectangular prism in php

To find the volume of a rectangular prism in PHP, you can use the formula V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height of the rectangular prism.

Here's the code to find the volume of a rectangular prism in PHP:

main.php
<?php

// Define the dimensions of the rectangular prism
$length = 5;
$width = 3;
$height = 4;

// Calculate the volume of the rectangular prism
$volume = $length * $width * $height;

// Display the result
echo "The volume of the rectangular prism is " . $volume . ".";

?>

In this example, the length of the rectangular prism is 5, the width is 3, and the height is 4. The code calculates the volume using the formula V = l x w x h and stores the result in the $volume variable. Finally, the echo statement displays the result to the user.
