You have to split these complex shapes into parts and find the volume of each part. Then, add the parts' volumes together, which will be the total volume of these. The equation is V=bhw. V means volume, b means base, h means height, and w means width. Hope this helps!
A scale factor of less than one will shrink a figure. A scale factor more than one will enlarge a figure. A scale factor of one will keep the figure the same. Shrink, enlarge, same
