@JoannaBlackwelder Could you help me please?

danjs · Answer

you see you need to calculate the volume of the thing first?

joannablackwelder · Answer

Sure, can you draw a picture of the rectangular prism?

joannablackwelder · Answer

Or finding the total volume is a good way to start too.

danjs · Answer

volume of the prism divided by that cube volume,  rounded to higher whole
