Answer:
The final step in determining the volume of the pyramid is V = one-third (30) (12).
Step-by-step explanation:
Given : Abdul started solving for the volume of the pyramid using the steps below. V = one-third B h
A rectangular pyramid with a base of 10 meters by 3 meters and a height of 12 meters.
To find : What is the final step in determining the volume of the pyramid?
Solution :
The volume of pyramid is V = one-third B h
The base is B=(3) (10) = 30 meters squared
The height is h=12 meters
Substitute the value,
V = one-third (30) (12)
Therefore, the final step in determining the volume of the pyramid is V = one-third (30) (12).
So, option 1 is correct.
So the circumference is 9.42 then 91/9.42 = about 9
Answer: 120 units3
Explanation: When finding the base of a prism, you must always multiply the side with the right angle. So basically, 5 is ignored because it does not have a right angle.
1st step: 3*4=12
2nd step: 12/2=6 (because the tringle which is the base is half a square)
3rd step: 6*20=120
The ending is unit 3 because it is volume. Area is unit 2 and we don't know if the prism is in cm so it is not A, or B, and D is the incorrect answer.
In conclusion:
120 units 3
