What is the surface area of the pyramid?? pls help

39 square feet

Step-by-step explanation:

Area of square in the center:

3ft x 3ft = 9ft

Area of all four triangles:

3 x 5 then divide by 2 = 7.5

The 7.5 is the area of one triangle, so you need to multiply by 4 to get the surface area of all four triangles

7.5 x 4 = 30

Then add the 30 and 9 together to get the total surface area.

Which is 39 square feet

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
