Answer 1

If you're drawing a picture of the figure, let me say it'd be easier to post a picture using the "Attach File" button.

Answer 2

Abraham your back :o

Answer 3

First one: Surface Area = 2 * ( 28 * 8 - 4 * 4 - 20 * 4 + 28 * 4 + 8 * 4 )

Answer 4

Or First one: Surface Area = 2 * ( 8*4 + 24 * 4 + 28 * 4 + 8 * 4 )

Answer 5

Second one:
Surface Area = 2 * ( 6*4 + 6*3 ) + 4*3 + lateral surface area of rectangular pyramid.

Lateral surface area of rectangular pyramid = \(\sqrt{4^2+2^2} * 3 + \sqrt{4^2+1.5^2} * 4\)
