Question

A certain building is a rectangular solid with a square base of side length 25m and a volume of 13,000m3. What is the volume, in cubic meters, of a building that has a square base with a side of 75m and the same height as the other building?

Answer 1

In the first building volume is lbh so he gave us that the base is square so it’s l & b are equal.

V=13000

L=25
B=25
H=?

13000=(25)(25)(h)
13000=625h
H=13000/625
H=20.8


In the second building the height is same as first building. The base is square so, l and b are equal.

V=13000

L=75
B=75
