ANSWER: 1752
So I divided the figure into two the triangle was separate from the rectangle. Then I multiplied the sides of the rectangle 10 times 8 and got 80 and since there are two sides I timed that by two. Then the front and the back and got 256 and timed that by two. Then the bottom and the top and got 320 and also timed that by two then I added those up. Next I worked on the triangle and timed the from and the back and timed 12 and 20 then divided it by 2 because its a triangle and got 120 and since there was another one I timed it by 2. Then came the sides and I timed 20 and 10 then divided it by 2 and timed it by 2 since there were two sides then I added those with the rectangle and got my answer.
