Answer:
Step-by-step explanation:
The side of the square base is:
The formula for the surface area of the pyramid is:
The height is cleared in the previous expression:
![h = \sqrt{\frac{4}{9}\cdot \left[\frac{224\,cm^{2}-(8\,cm)^{2}}{8\,cm}\right]^{2}-\frac{1}{4}\cdot (8\,cm)^{2} }](https://tex.z-dn.net/?f=h%20%3D%20%5Csqrt%7B%5Cfrac%7B4%7D%7B9%7D%5Ccdot%20%5Cleft%5B%5Cfrac%7B224%5C%2Ccm%5E%7B2%7D-%288%5C%2Ccm%29%5E%7B2%7D%7D%7B8%5C%2Ccm%7D%5Cright%5D%5E%7B2%7D-%5Cfrac%7B1%7D%7B4%7D%5Ccdot%20%288%5C%2Ccm%29%5E%7B2%7D%20%7D)
The formula of finding volume is <em>l x w x h</em>.
So now just plug in the numbers they gave.
5 x 10 x 2 = 100.
The volume of the rectangular prism is 100 ft^3.
The price per foot would be .84 cents, 1 yard equals 3 feet so 2 yards is 6 feet. if you take $5.04 and divide it by 6 then you get 0.84
The sum of interior angles of a triangle is 180°, and a linear pair is supplementary (adds to 180°). The appropriate choice is
... G. w = 105°, because ...
_____
In short, an exterior angle is equal to the sum of the opposite interior angles.
... w = 180 - (180 - (45 + 60)) = 180 -180 +45 +60
... w = 45 +60
