Hello SDN community,
I have just begun studying for the physics portion of the MCAT and I am using Nova's MCAT Physics book.
I came across a relatively simple problem (but a problem nonetheless) which I want to run by you all:
Page 8 Question 19
Given the formula for the volume of a pyramid with a square bas:
V = (1/3) s^2 h
s = length of a side, h = perpendicular height
If every linear dimension of a square pyramid were increased by a factor of 3, how would the volume change?
a increase by a factor of 3
b increase by a factor of 9
c increase by a factor of 27
d increase by a factor of 81
The text says that the answer is C. But this does not take into account the (1/3) in the problem. Why would the answer not be B? Any thoughts?
Thanks in advance for your help.
