Building 1 has a square base of length 25 hence width will be 25 as well.
Building 2 has a square base of length 75 hence width will be 75 as well.
Height for both the building is same.
Now the volume is calculated as V = length * width * height
We can see that for building 2, length is 3 times the length of first. Same goes for width.
So the volume of building 2 will be 3 * 3 = 9 times the volume of the first building.
Hence volume of building 2 = 3 * 3 * 13000 = 117,000
Answer D

For the 1st Building:
Square base with side = 25 meters.
Therefore the base is \(25*25\) = \(625\) \(m^2\)
Volume of the building is given as: \(13000\) cubic meters.
Hence, Height of the building can be found out with
H = \(\frac{13000}{625}\) = \(20.8
\)
For the 2nd Building:
The height is the same as the 1st building
The side of the square base is 75 meters.
Volume of the building is \(75*75* 20.8\) = 117000 cubic meters.
