Complete question:What is the surface area of the 8-sided figure?
Step-by-step explanation:
Consider the half of the 8-sided die i.e the pyramid ABCDE:
As the base is 6 of the perimeter, so each side of the base is 6/4=3/2
Now, the distance between the tallest points is 2 cm, so the height of Pyramid ABCDE is 1 cm.
Considering the right triangle EOM:
EO=1, OM= 3/4 (it is half of AB=3/2) and EM is the hypothenuse, so by the pythagorean theorem length of EM is

5. So side EBC has area

6. The total area is 8*Area(EBC)=

To start, determine how much a non-college graduate would earn over a 40 year period by multiplying their yearly salary by 40, 30,000*40=120,000. Next, increase it by 30%. Do this by taking 30% of 120k to find out how much more money you would make in comparison to a non-college grad, 120,000*.3=36,000. This means a college grad would make $36,000 more than a non-college grad.
