The Great Pyramids of Khufu is located in El Giza, Egypt. Pyramids were built to serve as tombs for the pharaohs of ancient Egypt. The Great Pyramid is 481 feet high and has a square base with a base edge length of 756 feet. What is the approximate surface area (to the nearest hundredth) of the pyramid.


(HINT: is the base on the surface?)​

Answer 1

Answer:

Square base with edge length =756 feet

area of square =s×s=756×756=571,563ft²

⇒area of base=l/2=756/2=378ft

By pythagorean therom

H²=p²+B²

(481)²=p²+(378)²

p²=(481)²-(378)²

p²=231,361-142,884

p²=88,477

p=√88,477

p=297.45

Area of triangle =1/2×b×h

=1/2×297.45×481

=148.725×481

=71,536.725

Now 4 area of triangle=4×71,536.725

=286,146.9ft

total surface area of pyramid +squre

=751,563+286,146. =1,037,709,9ft.

HOE THIS WILL HELP YOU.

Answer 2

Question:-

The Great Pyramids of Khufu is located in El Giza, Egypt. Pyramids were built to serve as tombs for the pharaohs of ancient Egypt. The Great Pyramid is 481 feet high and has a square base with a base edge length of 756 feet. What is the approximate surface area (to the nearest hundredth) of the pyramid.

Answer:-

Side = 756 feet

area of square,

=> Side² = 756 × 756 = 571,563ft²

=> area of base = 1/2 = 756/2 = 378ft

By pythagorean theorem,

H² = P²+B²

(481)² = P²+(378)²

P² = (481)²-(378)²

P² = 231,361-142,884

P² = 88,477

P = √88,477

P = 297.45

Area of triangle =1/2 × b × h

=> 1/2x297.45*481

=> 148.725×481

=> 71,536.725

Now 4 area of triangle = 4×71,536.725

=> 286,146.9ft

total surface area of pyramid + square

=> 751,563 + 286,146.

=> 1,037,709,9ft.

$\boxed{1,037,709,9ft}$
