<h3>Answer: 576 </h3>
============================================================
Check out the diagram below.
I've split the figure into 3 separate blocks. We calculate the volume of each block, then add up those volumes to get the final answer.
- Block A = largest block on the left
- Block B = middle block
- Block C = smallest block on the right
So,
- volume of block A = length*width*height = 6*6*8 = 288 ft^3
- volume of block B = length*width*height = 6*6*5 = 180 ft^3
- volume of block C = length*width*height = 6*6*3 = 108 ft^3
Therefore, the total volume we're working with is:
A+B+C = 288+180+108 = 576 cubic feet
The "cubic feet" or "ft^3" portion is already taken care of by your teacher, so you just need to type in the number itself.
