Answer:
If you mean the sum of internal angles of the n-gon is 6 right angles,
we use the formula 180*(n-2) = 6*90
or n-2 = 6*90/180
or n - 2 = 3
or n = 5
So it is a pentagon or 5-gon
The answer would be D, 4,096 because you would multiply each side by 8 and the gives you 16. Volume=length times width times height, so 16 cubed=4,096
the answer are 4kg ,12kg and 20 kg
