Answer:
1442
Step-by-step explanation:
Given,
Mean is,

Standard deviation,
,
Margin of error(E) = 0.54,
For 98% level of confidence, 
Thus, the sample size would be,
![n=[\frac{z_{\frac{\alpha}{2}}\times \sigma}{E}]^2](https://tex.z-dn.net/?f=n%3D%5B%5Cfrac%7Bz_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%7D%5Ctimes%20%5Csigma%7D%7BE%7D%5D%5E2)
![=[\frac{2.33\times 8.8}{0.54}]^2](https://tex.z-dn.net/?f=%3D%5B%5Cfrac%7B2.33%5Ctimes%208.8%7D%7B0.54%7D%5D%5E2)


V=LWH
small=12*8*4=384
large=20*15*9=2700
space=large-small
space=2700-384
space=2316
there is 2316in^3 left
Number 1 might be A and number 2 might be B. I'm not sure though.
Answer:
A. 2468 sq. ft.
Step-by-step explanation:
I calculated it logically
60% = 60/100 = 6/10 = .6
These are the forms 60% can be written in, 6/10 is the simplest fraction form. Hope this helps! :)
