Answer:
The surface area of the great pyramid is 192,776m.
Step-by-step explanation:
how do you find the area of a square is you multiply The base times the height and you get the area of a square so 230m Times 230m=52,900
and how you find The area of a triangle is multiply the base times the height And then VERY VERY IMPORTANT DEVIDE BY 2 then in your case since all the triangles are the same you multiply by four.
187m×187m= 34,969x4= 139,876
then you add it all together 139,876+52,900= 192,776
BTW very high stakes I wish you the best of luck!!!
