Given:
The figure of a square base pyramid.
To find:
The area of volume of the pyramid.
Solution:
The area of square base is:



Area of one triangular side of the pyramid is:



Now, the total surface area of the pyramid is:




Therefore, the surface area of the pyramid is 672 square m.
The volume of the pyramid is:

Where, B is the base area and h is the vertical height of the pyramid.
Substituting
, we get



Therefore, the volume of the pyramid is 512 cubic meters.
Hence the correct option is d.
Gym A charges $ 9 per hr......1 hr = 60 minutes
9/60 = 0.15 per minute
Gym B charges 0.75 per 5 minutes
0.75/5 = 0.15 per minute
both Gyms cost the same
Answer:

Answer:
5/6
Step-by-step explanation:
1/2 + 1/3 need a common denominator to add them up.
1/2 is the same as 3/6.
1/3 is the sane as 2/6.
3/6 + 2/6
Add the tops, but keep the same denominator.
3/6 + 2/6 = 5/6
5/6 cannot be simplified, so that's the answer. That's how you do it! Hope this helps!
