To find the surface area of a square pyramid, we use the formula: Surface Area = Base Area + Lateral Area. The base area is length times width (12 inches x 12 inches = 144 square inches), and the lateral area can be found by first calculating the slant height (using the Pythagorean theorem, which gives us about 20.8 inches), and then using the formula for lateral area (1/2 × perimeter of the base × slant height), which would be (1/2 × 48 inches × 20.8 inches = 499.2 square inches), so adding the base area gives us the total surface area of about 643.2 square inches.
Calculate the surface area of the square pyramid that has a base length of 12 inches and a height of 18 inches. Show your work by plugging in the dimensions of the pyramid into the correct surface area formula. Explain each step of your solving process. make it sound 7th grade and 2 sentences long
