<h3>What is the volume of a rectangular prism?</h3>
The volume of a rectangular prism of length l, width w and height h is given by:
In this problem, both the hole and the open-box bed are rectangular, hence the number of trips is the ratio between the volumes of the hole and of the open-box bed.
<h3>What is the volume of the volume of the hole?</h3>
The dimensions in meters are , hence:
<h3>What is the volume of the volume of the open-box?</h3>
The dimensions in meters are , hence:
<h3>What is the ratio of the volumes?</h3>
It's their division, hence:
