Apicture shows the net of a pyramid. three statements about this pyramid are true. which statement is not true?
a: the slant height of the pyramid is 12 in.
b: the total surface area of this pyramid is (5 x 5)in. + (.5 x 5 x 12)in
c: the area of the base is 25 in.

We can immediately confirm C is TRUE because the base is simply 5x5=25 square inches.
Now looking at A, the definiton of "slant height" is that if you ran a ruler up one of the sides of the pyramid, thats it. So imagine building this net, the red line would be referring to the slant height, A is TRUE.

B is NOT TRUE.

In fact, the equation of the surface of the pyramid is far more complicated than the one proposed in the question. For reference, the area of a pyramid is given by:
