	Cubul este: 1) prisma patrulateră regulată, dreaptă, cu toate muchiile congruente; 2) prisma patrulateră regulată, dreaptă, cu &icirc;nălțimea egală cu latura bazei; 3) paralelipipedul cu dimensiunile egale, respectiv, L = l = i; 4) hexaedrul cu fețele pătrate congruente.</p>
<p>
	&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<img alt="" src="http://iteach.ro/mod/CKEditor/image_viewer.php?file_guid=53338" style="width: 165px; height: 171px;" /></p>
<p>
	Elementele cubului sunt: a) cele opt v&acirc;rfuri; b) cele douăsprezece muchii; c) cele șase fețe; d) cele patru diagonale, concurente &icirc;n centrul cubului.&nbsp;</p>
<p>
	C&acirc;teva aplicații foarte interesante ale cubului sunt: jucării; cubul logic, din bile; cubul Rubik; structuri Soma; construcții ș.a.</p>

	Iată c&acirc;teva imagini:</p>
