A pyramid shaped building is 311 feet tall and has a square base with sides of 619 ft. The sides of the building are made from r
zmey [24]

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;

l^{2} = 311^{2} + 309.5^{2}

   = 96721 + 95790.25

   = 192511.25

⇒ l = \sqrt{192511.25}

      = 438.761

The slant height, l is 438.8 feet.

Considering one reflecting surface of the pyramid, its area = \frac{1}{2} × base × height

  area =  \frac{1}{2} × 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
