Answer:
The width of the actual fence is 90ft
Step-by-step explanation:
If 2in = 10ft, you want to find the scale factor. To do this, you need to divide 10/2, so for every 5ft, it is 1in. Now, you would take how many inches you have and multiply it by 5. (in our case, 18in)
18 x 5 = 90.
So the actual fence length is 90ft.
Answer:
Step-by-step explanation:
You need to use the following formula to calculate the volume of Triangular prism:
Where "a" is the area of one triangular base and "h" is the height of the triangular prism.
Calculate "a" with this formula:
Where "b" is the base of the triangle and "H" is the height.
In this case:
Then, substituting values, you get that the area is the following:
Finally, you must substitute values into the formula for calculate the volume of the triangular prism, and you also must substitute , which is its height:
