Question

The Great Pyramid of Giza is an example of a square pyramid and is the last

surviving structure considered a wonder of the ancient world. The builders of the

pyramid used a measure called a cubit, which represents the length of the forearm

from the elbow to the tip of the middle finger. One cubit is about 20 inches in length,

One side of the base is measured to be 453 cubits and the lateral surface area is 260,928 squared cubits.


What is the surface area?

Answer 1

The surface area of the pyramid is 466,137 squared cubits

Explanation:

This is simply asking us to find the surface area of the square based pyramid with the given dimensions.

The first thing we need to know is the principle for finding the surface area of such pyramidal shapes. To get the surface area of a pyramid, we will have to add the base area to the area of the side faces ( lateral area)

The base area of the square based pyramid, will be the same as the area of a square which is = 453 cubits X 453 cubits =
`205209 cubits^(2)`

The lateral area has already been given to us as 260,928 squared cubits.

The surface area of the pyramid is 260,928 + 205209 = 466137 squared cubits

Hence, the surface area of the pyramid is 466137 squared cubits
