Step-by-step explanation:
Cubes have square faces, so the area of the base is b².
The volume of the cube is b³.
The height of each pyramid is half the height of the cube, so h = b/2. Which means b = 2h.
The cube is made of 6 square pyramids with the same base and height. Therefore, each pyramid has 1/6 the volume of the cube. So the volume of each pyramid is b³/6.

1,2,4
Step-by-step explanation:
<em>A chord of a circle is a straight line segment whose endpoints both lie on the circle. </em>
<em>KJ is CHORD</em><em>.</em>
<em>Tangency is point where tangent of circle touch it. </em>
<em>F is point of Tangency for FE.</em>
<em>Secant is the infinite line extension of a chord.</em>
<em>GN is a secant segment. </em>

We know that time is distance over velocity, that is:
time = distance / velocity
t = d / v
Now from the given:
d / 460 + d / 500 = 4.8
Now we can find for d:
d = 4.8 / [1/460 + 1/500]
d = 1150 miles
So the time of each flight is:
flight = 1150 / 460 = 2.5 hours
<span>return flight = 1150 / 500 = 2.3 hours</span>
