The volume of the pyramid is 80 cubic centimeters.
Step-by-step explanation:
As the formula for the volume of a pyramid is 1/3bh, so if all the dimensions are the same for both figures, just divide the volume of the prism by three to find the volume of the pyramid. If you do this 240÷3=80 or the volume of the pyramid.
 
        
                    
             
        
        
        
It should be A= 1/2bh but im not sure why you wrote those extra things. Are we supposed to use them?
