Surface area is just the area of the shapes used to make this figure

Lets start with the top and bottom rectangle which are the same
What would be the area of two 4x8 rectangles?

Answer 6

And yea. I could check your answer

Answer 7

for the rectangular prism (top, bottom, two side) [2x8x4] + [2x4x10] = 144
for the faces of the rectangular prism 2[8x10 - 3.14x2^2] =134.88
for the cylinder WxL 4[2x3,14x2] = 50.24

so the total surface area will be
144+134.88+50.24 = 329.12

let me know if I did anything wrong please
