Slant height of a pyramid
The ratio of the height of the pyramid to the edge of the square base is 1.5 to 1. The height of the pyramid is 3 meters. What is the approximate length of the slant height of the pyramid?
A. 4.4 m
B. 3.2 m
C. 2.8 m
D. 1.4 m
I am not sure what the ratio part means, but I thought maybe
using a proportion
and then using a triangle (pyth. thm.) 3^2 + 2^2 = c^2 (slant height)
so I got sqrt (13) which equals 3.6
which the answer is supposed to be 3.2 but I do not think I did this correct because the answers are not close enough.
