<span>so.... </span> <span>LCD of 2,3,4,5,6,7,8,9, and 10 is 2520 </span> <span>so she had 2521 marbles in her bag. </span>
<span>check a few of them by dividing 2521 by any number from 2 to 10</span>
You can multiply each of these values together to get the volume of the rectangular prism. The volume of the rectangular prism is 10 cubic units or units3. The units are cubic units because you multiplied the units 3 times when you multiplied the height, length, and width.
