Thank you so much you are a life saver

Sure, I can help @Les. So, number 6 asks you to find the surface area of another similar pyramid. What you want to do, is take the smaller pyramids surface area and put it over the larger ones. We know that it is 90 in^2, however we do not know the larger...

No man, that is not correct! It is D.Pyramid. Please do not trick people like that if you are unsure of the answer! Explanation: A pyramid does not have two bases, only one. Therefore, it cannot have two parallel bases.

Actually, it can. Think about it. Cylinders have two bases that are circles. Those circles are also parallel. It should be pyramid, because a pyramid has only one base.

Jeez, I'm surprised nobody knows. I do though, so here is the answer. It is 6ft. Set up a proportion and solve people!

I'll 171th that!
