The surface area of a pyramid can be calculated using the formula:
Surface Area = 0.5 * base perimeter * slant height + base area
First, calculate the base perimeter of the pyramid:
Base perimeter = 4 * 10m = 40m
Next, calculate the slant height of the pyramid:
Slant height = sqrt((12m)^2 + (5m)^2) = sqrt(144 + 25) = sqrt(169) = 13m
Now, calculate the base area of the pyramid:
Base area = 10m * 10m = 100 square meters
Finally, calculate the surface area of the pyramid:
Surface Area = 0.5 * 40m * 13m + 100 square meters
Surface Area = 0.5 * 520 square meters + 100 square meters
Surface Area = 260 square meters + 100 square meters
Surface Area = 360 square meters
Therefore, the surface area of the pyramid is 360 square meters.
What is the surface area, in square meters, of the pyramid?
10m is the square and 12m is the pyramid
