Answer:
Explanation:
Hello!
Height of pyramid = 845 feet
Slant height = 856 feet
width = 175 feet
The surface area of a pyramid = The base area of the pyramid added to the area of the 4 triangles.
The volume of a pyramid = 1/3 base area * height
1 Triangle = 1/2 base * height
Triangle = 1/2 * 175 * 856 feet
1 Triangle Area = 74,900 feet
The area of 4 triangles = 299,600 feet
Now, the area of the base = is 175 * 175 feet
Base area = 30,625 feet
Surface area = 30,625 + 299,600 feet = 330,225 feet
Volume = 1/3 * Base area * height of pyramid
Volume = 1/3 * 30,625 feet squared * 845 feet
Volume = 1/3 * 25,878,125 feet cubed
Volume = 8,626,041.(6) feet cubed
Hope i helped!
