Answer:
A(total) = 528,000 feet^2
Step-by-step explanation:
The slant height of each of the four triangular sides is given and is 440 feet. The length of the base of each is 600 feet. We apply the formula for the area of a triangle, which is A = (1/2)(base)(height):
Area of one triangular side: A = (1/2)(600 feet)(440 feet) = 132,000 feet^2.
The total glass area of the pyramid is thus four times this, or
A(total) = 528,000 feet^2
