find the volume of a cube in php

To find the volume of a cube in PHP, we can use the formula:

main.php
volume = side * side * side
28 chars
2 lines

where side is the length of a side of the cube.

Here's the PHP code to calculate the volume of a cube:

main.php
<?php
$side = 5;
$volume = $side * $side * $side;
echo "The volume of the cube is " . $volume;
?>
98 chars
6 lines

In this example, we have assigned the value of 5 to $side which is the length of a side of the cube. We then use the formula to calculate the volume and store it in the variable $volume. Finally, we use echo to display the calculated volume on the screen.

You can change the value of $side to any other value to calculate the volume of a cube with a different side length.
