Find the volume of a pyramid with a square base, where the perimeter of the base is 15.4 and the height of the pyramid is 13.1. Round your answer to the nearest tenth of a cubic meter.

Respuesta :

Answer: 69.3

Explanation: So if the height is 13.1, that means that the length is 2.3. And to find volume, you do length times width times height. So the width would be 2.3 because it is a even square if that makes since. Now 2.3 times 2.3 is 5.29. Now we multiply 5.29 by 13.1. The answer is 69.299. Now we round this to the nearest tenth, so the answer would be 69.3.

Answer: 64.7249167 = 64.7

Step-by-step explanation:

15.4

15.4 / 4 = 3.85

3.85^2=14.8225

1/3 (14.8225)(13.1)

64.7249167 = 64.7
