Question 590723: Finding volumes, lateral areas and total areas of pyramids?
I've been resolving these problems over and over again since yesterday morning. I've spent 26 hours (20 yesterday, 6 today) in this class trying to stay positive while only messing up again and again. Well i'm tired now. Could someone help me with these please? On how to solve these? I don't need an exact answer, even if it's just some steps into it i'd be the most grateful.
