Answer:
<h2>36ft cubed</h2>
Step-by-step explanation:
The total volume is 36ft. In order to find the volume, you can split this up into 3 boxes.
The first box go with the dimensions of 3ft (length) by 2 ft (width) by 1ft (height), multiply that, you get 6ft
The second box go with the dimensions of 3ft (length) by 4ft (width) by 1ft (height), multiply that, you get 12ft
The third box go with the dimensions of 3ft (length) by 6ft (width) by 1ft (height), multiply that, you get 18ft
Lastly, add together the 3 boxes, (6+12+18), which you get 36ft, and since this is volume, it is 36ft cubed
