Answer:
256,096 ft²
Explanation:
Pyramid Area
Each of the four faces is a triangle with a base of 756 feet and a height of 612 feet. The area of that triangle is ...
A = 1/2bh
A = 1/2(756 ft)(612 ft) = 231,336 ft²
The total area of the four visible faces of the Great Pyramid is ...
pyramid area = 4 × 231,336 ft² = 925,344 ft²
__
WTC Area
Each of the four rectangular side faces of the WTC tower has a base length of 208 ft and a height of 1368 ft. The area of it is ...
A = LW = (208 ft)(1368 ft) = 284,544 ft²
The area of the square top of the tower has an area that is ...
A = s² = (208 ft)² = 43,264 ft²
The total area of the four visible sides and the top is ...
WTC tower area = 4 × 284,544 ft² +43,264 ft² = 1,181,440 ft²
__
The difference between the areas is ...
WTC tower area - Great Pyramid area =
1,181,440 ft² -925,344 ft² = 256,096 ft²
The difference in visible area is 256,096 ft².
