Surface area break it down bottom and top bottom=5 rectangle top=2 triangles+2rectangle areas area of recatngle=lw area of traignle=1/2lw
so total is SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8) (I'm not going to do all the math, just the result) SA=178.08 yd^2
split the figure into 2 parts top and bottom bottom=rectagular prism=lwh top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so
bottom=8 times 2.8 times 4.8=107.52 top=1/2 times 8 times 3 times 2.8=33.6 add them 107.52+33.6=141.12 yd^3
