Answer:
The slant height is 28 inches
Step-by-step explanation:
The slant height of a pyramid
Given a square base pyramid of side 2a and height h, the slant height is calculated as follows:
[tex]s=\sqrt{a^2+h^2}[/tex]
The attached image shows the relationship between the lengths.
There is no specific information about the dimensions provided in the question, but I'm assuming this:
h = 22.4 in
a = 16.8 in
The slant height is:
[tex]s=\sqrt{16.8^2+22.4^2}[/tex]
[tex]s=\sqrt{784}[/tex]
s = 28 in
The slant height is 28 inches
