Use the image to answer the question.
An illustration shows a pyramid with a rectangular base of length 8 feet and width 6 feet. The perpendicular height, drawn as a dotted line from the apex to the center of the base, is labeled 12 feet. The sides that are not visible are drawn in dashed lines.
What is the pyramid’s length?

My apologies for the error. Let's calculate the length of the pyramid's slant height.
The slant height can be found using the Pythagorean theorem, where:
slant height (s) = √(base length/2)^2 + height^2
s = √(4^2 + 12^2)
s = √(16 + 144)
s = √160
s ≈ 12.65 feet
Therefore, the length of the pyramid's slant height is approximately 12.65 feet.
