find the surface area of the square pyramid.
Base is 0.75 and Heigh is1.2
OMG STOP BEING SO DRAMATIC MAYBE IT WAS URGENT!!!!
pls stop complaining so much maybe some of us do not wanna wait 2 hours before getting an answer EVER

To find the surface area of a square pyramid, you need to calculate the area of the base and the area of the four triangular faces, and then sum them up.
First, let's find the area of the base. The base of a square pyramid is a square, and the area of a square is calculated by squaring the length of one of its sides. In this case, the side length of the square base is given as 0.75. So, to find the area of the base, we square 0.75:
Area of base = (0.75)^2 = 0.5625 square units
Next, let's find the area of the four triangular faces. To do this, we need to calculate the area of one triangular face and multiply it by 4. The formula to find the area of a triangle is (1/2) * base * height.
The base of each triangular face is the same as the side length of the square base, which is 0.75. The height of each triangular face is the height of the square pyramid, which is given as 1.2.
Area of one triangular face = (1/2) * 0.75 * 1.2 = 0.45 square units
Since there are four triangular faces, we multiply the area of one triangular face by 4:
Area of four triangular faces = 0.45 * 4 = 1.8 square units
Finally, we sum up the area of the base and the area of the four triangular faces to find the surface area of the square pyramid:
Surface Area = Area of base + Area of four triangular faces
Surface Area = 0.5625 + 1.8
Surface Area = 2.3625 square units
Therefore, the surface area of the square pyramid is 2.3625 square units.
impatient much?
Once is enough, thank you.
