657.1 ?
As so get the surface area you do widths X length X height and you split the diagram so you only have to work out the cube and the prism by themselves, then you add them together to get 657.135 and rounding to the nearest tenth would be 657.1 I think :))
Well 10x2 is 20 so 10 is your answer hope this helps
Hi,
Your answer would be: −2x4+10x3−21x2+19x−4
Hope I could help!~ have a good day/night :]
