Hi!
To find the volume of this solid, you need to find the volume of the entire prism, then subtract the volume of the cube that was removed.
Total solid volume = Prism volume - Cube volume
Here are the volume formulas you'll need:

By inserting these formulas into our equation, we get:
Total solid volume = Prism volume - Cube volume
Total solid volume = \((A_{b}\times h ) - (c^3)\)
We can now insert the known values into our equation.

Which gives us :
Total solid volume = \(((6\times 4)\times 1 ) - (2^3)\)
I'll let you complete. I hope this helps! If you have any other questions, feel free to write to us again! :)
