What is the volume of the composite figure?

55 cubic yards 
120 cubic yards
135 cubic yards
167 cubic yards

Please help. Don't just give me the answer. Help.

Okay...so I think the way you do this is by finding the volume of both figures (seperately) then add them. :)

So you would be finding the volume of the pyramid first...then find the volume of the rectangular prism next...combine the two volumes by adding. :)

Remember...
$$Volume~of~pyramid=\frac{ lwh }{ 3 }$$$$Volume~of~Rectangular~Prism=lwh$$

Ur welcome!  I like to explain when I can. c:

Let me check if you got it right because I didn't solve it, I just gave you the rule for when finding the volume of composite figures. :)

hugsnotughs · Answer

So...

Volume for Rectangular Prism:  120
Volume for Pyramid:  15

120 + 15 = 135.  Correct! :D
