Answer: Explained.
Step-by-step explanation: We are given to explain the importance of using net in finding the surface area of prisms and pyramids.
With the help of net, we can easily see the different sides, faces and angles of a prism or pyramid.
For example, see the attached figure, where the nets of both prism and pyramid are shown.
With the help of these figures, we can easily calculate the surface area by finding the surface area of each face of the prism or pyramid.

Answer:
5 minutes to run 1 kilometer
Step-by-step explanation:
Alonzo takes 12 minutes to run 6 times around a 400-meter track.
6 times around a 400 m track
400 * 6 = 2400 meters
It take 12 minutes to run 2400 meters
2400 meters = 2400/1000 = 2.4km
distance = 2.4 km and time = 12 minutes
Now we find our constant speed
2.4 = speed * 12
divide by 12 on both sides
speed = 0.2
so speed is 0.2 km per minute
Now we find out time when distance = 1km
Distance = speed * time
1 = 0.2 * t
divide by 0.2 on both sides
5 = t
So it take 5 minutes to run 1 kilometer
