The areas of the square pyramid are the amount of space on it
- The lateral surface area is 307.2 square cm
- The total surface area is 451.2 square cm
<h3>How to determine the lateral surface area?</h3>
The given parameters are:
Base (b) = 12 cm
Slant height (l) = 12.8 cm
The lateral surface area is calculated using:
L = 2bl
So, we have:
L = 2 * 12 * 12.8
Evaluate the product
L = 307.2
<h3>How to determine the total surface area?</h3>
This is calculated using:
T = L + b^2
So, we have:
T = 307.2 + 12^2
Evaluate
T = 451.2
Hence, the total surface area is 451.2 square cm

Answer:
Speed of one dog is 2.5 m/s and other dog is 5.5 m/s.
Step-by-step explanation:
Total distance between the two dogs = 360 m
Let the speed of one dog be x m/s, then the speed of second dog will be x+3 m/s.
Then total speed of two dogs = x+x+3 = 2x+3
Times = 20 seconds
After 20 seconds, distance left between them = 200 m
Distance traveled by the two dogs in 20 seconds = 360 m - 200 m
= 160 m
We know, Speed = 
2x+3 = 
2x = 8-3 = 5
x = 2.5 m/s
Speed of first dog = 2.5 m/s
Speed of second dog = x+3 = 2.5 +3
= 5.5m/s
Speed of one dog is 2.5 m/s and other dog is 5.5 m/s.

Explicación paso a paso:
Dado :
Fracción de tiempo diario dedicado a publicidad = 1/8
Del tiempo diario dedicado a publicidad, 3/5 corresponde a comerciales de universidad
Fracción del tiempo diario dedicado a la publicidad de las universidades:
3/5 de 1/8
3/5 * 1/8 = (3 * 1) / (5 * 8) = 3/40
