Answer:
The answer is 445,446
Step-by-step explanation:
have a great day everyone :)
You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is:
10*sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10*1.414 = 14.14 ft or about 14 ft.
First we need to find the volume of the prism without the dilated factor:
The volume would be:
Volume of the prism(without dilated) = (area of the base) * (height)
Since,
Area of base = 5

Height of the prism = 10f
Volume(without dilated) = 5*10 = 50

Now let us apply the dilated factor! For that you need to multiply for factor with the volume of the prism without dilation.
Volume of the dilated prism =

* (Volume of the prism without dilation)
Where d = dilated factor. Therefore,

v = 86.4

So the correct answer:
86.4
X would be 4 because
2 times 4 is 8
So 8+8=16
16+1=17
