Question

The approximate measurements of the Great Pyramid of Khufu are shown below. A square pyramid. The base is 230 meters by 230 meters. The triangular sides have a base of 230 meters and height of 187 meters. The pyramid has a height of 147 meters. What is the surface area of the pyramid? 86,020 meters squared 138,920 meters squared 224,940 meters squared 2,592,100 meters squared

Answer 1

Answer:

138,920 m²

Step-by-step explanation:

A square pyramid has 1 square base and 4 lateral triangular faces.

Area of square pyramid is given as BASE Area (BA) + ½*Perimeter of Base (P) × Slant height

Area of pyramid = $b^2 + \frac{1}{2}*4(b)*l$

Where,

b = base length = 230 m

l = slant height = 187 m (height of the triangular sides)

Surface area = $230^2 + \frac{1}{2}*4(230)*187$

$= 52900 + 2(230)*187$

$= 52900 + 86020$

$= 138920$

Surface area of the pyramid = 138,920 m²
