The formula for the surface area of a square pyramid is given by:
SA = base area + (0.5 x base perimeter x slant height)
The base area is equal to the base edge length squared, so in this case, it is 5 yards squared:
base area = 5^2 = 25 square yards
The base perimeter is equal to 4 times the base edge length, so in this case, it is 4 x 5 = 20 yards.
The slant height can be found using the Pythagorean theorem. Since the base of the pyramid is a square, the height forms the hypotenuse of a right triangle with two legs of length 5 yards each. Therefore, we have:
height^2 = (leg1^2) + (leg2^2)
25^2 = 5^2 + leg2^2
625 = 25 + leg2^2
leg2^2 = 625 - 25
leg2^2 = 600
leg2 ≈ √600
leg2 ≈ 24.49
Now, we can substitute these values into the formula to find the surface area:
SA = 25 + (0.5 x 20 x 24.49)
SA = 25 + (0.5 x 20 x 24.49)
SA = 25 + 12.245
SA ≈ 37.245
Rounding to the nearest whole number, the surface area of the square pyramid is approximately 37 square yards.
Use the formula for the surface area of a square pyramid to find the surface area if the base edge length is 5 yards and the height is 25 yards. Round to the nearest whole number.
