Answer:
The lower level has a greater volume.
Step-by-step explanation:
<u><em>The question is incomplete, so the complete question is below:</em></u>
Andre and molly have a tree fort that consists of two rectangular rooms.The upper level has a length of 5ft, a width of 3ft and a height of 6ft .The lower level has a length of 6ft, a width of 5ft and a height of 8ft. Which level has a greater volume?
Now, to find which level has greater volume.
The dimensions of upper level has a length of 5ft, width of 3ft and a height of 6ft.
So, we get the volume of upper level by putting formula:



Now, to get the volume of lower level by putting formula:



<u><em>Now, we see the volume of upper level is 90 ft³ and volume of lower level is 240 ft³.</em></u>
<u><em>Hence, the volume of lower level is greater than volume of upper level. </em></u>
Therefore, the lower level has a greater volume.
