Question 112529
OK, a square pyramid has 5 faces- 4 of the same triangle and 1 base.  So, the surface area is the area of those 5 faces.  The base has an area of 751*751=564001ft^2 and each triangle  has an area of 1/2*751*610=229055ft^2.
So the surface area of the pyramid is 564001 + 4*229055 = 1480221 ft^2.
