1. Consider the pyramid ABCDE in the figure 1 attached:
Each side of the square base equals (units)
Area of 1 lateral side of pyramid ABCDE is
so the total lateral area is (units squared)
and the total surface area is (units squared)
2. Now consider the second figure KLMNP, Sydney's pyramid:
The lateral area is
so the total area of the second pyramid is
So 2 things can be said about the areas:
i) the lateral area of Sydney's pyramid is times larger than the lateral area of the original pyramid.
ii) The total area of Sydney's pyramid is units squared larger than the total area of the original pyramid.
Answer:
The correct answer is (b).
Step-by-step explanation:
A line is parallel to the axis if it has a slope equal zero. Then if we compute the slope of the line that joins the points
then
This implies that the line which that joins this points is parallel to the x-axis.
Observe that the slopes of the lines corresponding to the other items are nonzero.
