What is the total suraface area of the sequare pyramid below

C: 280

Explanation:

An explanation of this question is what is the total surface of the pyramid,

what I did was multiply 14 x 20. How did I get the 20, I got it because since the two sides on the bottom are equal, add the 10+10 and you have 20. So the equation should be 14 x 20.

(If this doesn't help I'm sorry).

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

what is shown in the image?

eukaryote

chloroplast

mitochondrion
