This is what I am trying to do. I would like my code to return the following:

> 
> "The volume of the small box is: 300"
> 
> 
> 

But I cannot seem to figure out what to do:

```
<?php
    $box = array(
       "Small box" => array("length" => 12, "width" => 10, "depth" => 2.5),
       "Medium box" => array("length" => 30, "width" => 20, "depth" => 4),
       "Large box" => array("length" => 60, "width" => 40, "depth" => 11.5)

    );
    foreach ($box as $number => $boxes)
    {
        echo "The volume of the "."$number"." is: \t";
        foreach ($boxes as $value)            
        {
            if (is_numeric($value))
            {
               $sum = array_product($boxes);
               echo "$sum";
            }
        }
        echo "<br />";
    }
    ?>

```
