The lateral area of a square pyramid is calculated by finding the area of the four triangular faces. Given that the base of the pyramid is a square, we can use the formula for the lateral area of a square pyramid:
L = 4s*h / 2
where s is the side length of the base of the square pyramid and h is the slant height of the pyramid.
If the slant height of the pyramid is 18.45 m and the side length of the base is 15 m, we can plug these values into the formula to find the lateral area:
L = 4 * 15 * 18.45 / 2
L = 1110 / 2
L = 555 m2
Therefore, the lateral area of the square pyramid is 555 m2, which is closest to 551 m2.
What is the lateral area of the square pyramid, to the nearest whole number?
