Step-by-step explanation:
find the cross sectional area which is the triangle
triangle = 1/2 x 8.2 x 6.4 = 26.24

Answer:
B. centroid
Step-by-step explanation:
you have to look at every angle
It would be 8 10/16 divided by 3. If you change 3 to 3/1, you could do k.c.f (keep, change, flip is a method we learned when dividing fractions.) Change 128/16 multiplied by 1/3. That means your answer would be 128/48. If you simplify that, it would be 2 2/3. Just change that to ounces and pounds, and I guess that's your answer. Sorry if it is wrong, but I hope this helped.
