It's not clear where point Y is located. If Y is the midpoint, and Y is on line XZ, then we can say that XY = 25 and YZ = 25 (since Y cuts XZ in half; the two equal portions are XY and YZ)
I'm using the segment addition postulate XY+YZ = XZ
However, all of this is based on the assumption that Y is the midpoint and on line XZ.
1. line AB
2. M, B, and D
3. A, B, and C
4. I don't recall, sorry ,:)
The general formula for the volume of a square pyramid is
V = (1/3)b^2 h
If b increase by 50% their new length = 3b/2
Therefore the volume of the new pyramid is
V = (1/3) (3b/2)^2 h
= (1/3) 9b^2 / 4 h
= 3/4b^2 h Answer
