Answer:
Surface area of the reflective glass is 543234.4 square feet.
Step-by-step explanation:
Given that: height = 311 feet, sides of square base = 619 feet.
To determine the slant height, we have;
=
+
= 96721 + 95790.25
= 192511.25
⇒ l =
= 438.761
The slant height, l is 438.8 feet.
Considering one reflecting surface of the pyramid, its area = × base × height
area = × 619 × 438.8
= 135808.6
= 135808.6 square feet
Since the pyramid has four reflective surfaces,
surface area of the reflective glass = 4 × 135808.6
= 543234.4 square feet
