The surface area of a pyramid can be found using the formula:
Surface Area = Base Area + (1/2) * Perimeter * Slant Height
In this case, the pyramid is a square pyramid, so the base area is the area of a square:
Base Area = side length squared = 0.8cm * 0.8cm = 0.64cm^2
The slant height is the height of each triangular face of the pyramid. Since the pyramid has a height of length 0.8cm, the slant height is also 0.8cm.
Perimeter = 4 * side length = 4 * 0.8cm = 3.2cm
Plugging these values into the formula, we get:
Surface Area = 0.64cm^2 + (1/2) * 3.2cm * 0.8cm = 0.64cm^2 + 1.28cm^2 = 1.92cm^2
Rounded to the tenth, the surface area of the square pyramid is 1.9 cm^2.
Surface Area = Base Area + (1/2) * Perimeter * Slant Height
In this case, the pyramid is a square pyramid, so the base area is the area of a square:
Base Area = side length squared = 0.8cm * 0.8cm = 0.64cm^2
The slant height is the height of each triangular face of the pyramid. Since the pyramid has a height of length 0.8cm, the slant height is also 0.8cm.
Perimeter = 4 * side length = 4 * 0.8cm = 3.2cm
Plugging these values into the formula, we get:
Surface Area = 0.64cm^2 + (1/2) * 3.2cm * 0.8cm = 0.64cm^2 + 1.28cm^2 = 1.92cm^2
Rounded to the tenth, the surface area of the square pyramid is 1.9 cm^2.

Apologies for the error in my response. Let's recalculate the surface area of the square pyramid correctly.
The base area of the square pyramid is given by:
Base Area = side length squared = (0.8cm)^2 = 0.64cm^2
The slant height is given as 0.8cm.
To find the perimeter of the base, we use the formula:
Perimeter = 4 * side length = 4 * 0.8cm = 3.2cm
Using the formula for surface area of a pyramid, we have:
Surface Area = Base Area + (1/2) * Perimeter * Slant Height
Surface Area = 0.64cm^2 + (1/2) * 3.2cm * 0.8cm
Surface Area = 0.64cm^2 + 1.28cm^2
Surface Area = 1.92cm^2
Rounded to the tenth, the surface area of the square pyramid is 1.9 cm^2, not 1.1 cm^2 as mentioned earlier. I apologize for any confusion caused.
