Answer:

Step-by-step explanation:
The formula of a surface area of a cube:

The formula of a volume of a cube:

We have

Calculate the edge length (<em>a</em>).
<em>divide both sides by 6</em>

Calculate the volume of a cube:

(5 radical 2)^2 =
5^2 × (radical 2)^2 =
25 × 2 = 50
Answer:
the angles in squares and rectangles it's always 90° so two squares or two rectangles with same side lengths are congruent.
F=m+25
m+f=139, using f from above we have:
m+(m+25)=139
2m+25=139
2m=114
m=57, and since f=m+25
f=82
So there are 57 males and 82 females.
