Best ResponseYou've already chosen the best response.0If it's what I think it is, it isn't 'hard', just finicky.

Best ResponseYou've already chosen the best response.0It comes down to the same principle we used to solve the last problem. You have faces that are shapes you already know the area of. You just break the surface area down into those shapes. Are you drawing something?

Best ResponseYou've already chosen the best response.0You have two rightangled triangles. These have a height of 6.4 and base 2. The area of any triangle is \[\frac{1}{2}(base)(perpendicular.height)\]Luckily, perpendicular height is the height of a rightangled triangle. So your area is\[\frac{1}{2} \times 2 \times 6.4=6.4\]You have two of these, one on the top, one on the bottom.

Best ResponseYou've already chosen the best response.0So the area of the triangular faces is 2 x 6.4 = 12.8. Put this aside and tackle the faces on the side.

Best ResponseYou've already chosen the best response.0These are just rectangles. Each has dimensions 6.4 x 2.9 = 18.56. Again, you have two of these, so your area for the sideon rectangular faces is 2 x 18.56 = 37.12.

Best ResponseYou've already chosen the best response.0Now all you gave left is the base. It is rectangular and has dimensions, 2 x 2.9 = 5.8. Can you see how the side length of the base is the same as the length of the prism at the top (where you've written 2.9)?

Best ResponseYou've already chosen the best response.0then just add them all up?

Best ResponseYou've already chosen the best response.0The total area is just the sum of these separate areas:\[12.8 + 18.56+5.8=37.16\]square units.
