A pyramid V-ABCD is cut from a cube of edge 12 in.,as shown in the figure. The

Question

vertex V is the midpoint of an upper edge of the cube. Compute the lateral surface of the pyramid.

Answer 1

draw the figure. Note that it is relatively easy to find the slope height of each face, by using the slope height as the hypotenuse of a right trangle whose legs are distances to a opposite corners.

area of each face then can be determined by Area face= 1/2 b*slope height.
add the four faces areas.

Answer 2

301.6 in^2

Answer 3

334.82 sq. in.

Answer 4
