<p class="larger">A <b>cuboid</b> is a box-shaped object. </p>
|
|
<p>It has six flat faces and all angles are <a href="../rightangle.html">right angles</a>.</p>
|
|
<p>And all of its faces are rectangles.</p>
|
|
<p>It is also a <a href="prisms.html">prism</a> because it has the same cross-section along a length. In fact it is a <b>rectangular prism</b>.</p>
|
|
<p> </p>
|
|
<h2>Examples of Cuboids</h2>
|
|
<p>Cuboids are very common in our world, from boxes to buildings we see them everywhere. We can even fit them inside other cuboids!</p>

<h2>Square Prism
|
|
</h2>
|
|
<p>When at least two of the lengths are equal it can also be called a <b>square prism</b>.</p>
|
|
<p>(Note: we can still call it a rectangular prism if we want!)</p>
|
|
<div style="clear:both"></div>
|
|
<p style="float:right; margin: 0 0 5px 10px;"><a href="hexahedron.html"><img src="images/blue-cube.jpg" width="190" height="190" border="0" alt="cube" /></a></p>
|
|
<h2>Cube</h2>
|
|
<p>When all three lengths are equal it is called a <b><a href="hexahedron.html">cube</a></b><a href="hexahedron.html"> (or hexahedron)</a> <br />
|
|
and each face is a square.</p>
|
|
<p>A cube is still a prism.</p>
|
|
<p>And a cube is one of the <a href="../platonic_solids.html">Platonic Solids</a>.</p>
|
|
<p > </p>
|
|
So:
|
|
<ul>
|
|
<div class="bigul">
|
|
<li>A cube is just a special case of a square prism, and<br />
|
|
</li>
|
|
<li>A square prism is just a special case of a rectangular prism, and<br />
|
|
</li>
|
|
<li>They are all cuboids! </li>
|
|
</div>
|
|
<br />
|
|
</ul>
|
|
<div class="words">
|
|
<p>Note: The name "cuboid" comes from "cube"<b> </b>and <i><b>-oid</b></i> (which means "similar to, or resembling") and so says "it is <i>like</i> a cube". </p>
|
|
<p>Another use of <b><i>-oid</i></b> is when we talk about the Earth being a spheroid (not exactly a sphere, but close).</p>

</div>

<a id="Area"></a>
|

<h2>Surface Area</h2>
|
|
<p>The surface area is found using the formula:</p>

|
|
<p> </p>

<p class="center">Which can be shortened to: </p>

<p align="center"><span class="largest">A = 2wl + 2lh + 2hw</span></p>
