Answer:
d(A,B)=1
Step-by-step explanation:
To find distance between points A(xA,yA) and B(xB,yB), we use formula:
d(A,B)=(xB−xA)2+(yB−yA)2−−−−−−−−−−−−−−−−−−−√
In this example: xA=3 , yA=5 , xB=3 and yB=6 so:
d(A,B)d(A,B)d(A,B)=(3−3)2+(6−5)2−−−−−−−−−−−−−−−√=0+1−−−−√=1

Use the distance formula:
A cube has 6 faces so:
Area of 1 face = 486/6 = 81 cm^2.
Lateral area = 4 * face area
= 4 * 81
= 324 cm2.

I think C
It has a whole number as numerator and denominator so it is rational and it is a real number, but it is not an integer because it is a fraction.
Answer: The answer is 90.
90+90= 180+90= 270
