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)=
Answer:
1.8.10=1.80000000000
7.2.10=7.2000000000
Step-by-step explanation:
Answer:
The first answer, 3 times the square root of x squared is correct.
You 2l x 2w and blah blah blah blah blah blah blah blah
X = 3 that is you x intercept
y = 2 that is your y intercept
