The Area of the square is (side)^2

side is given to be 2^(4/9)
SO,
side^2 = [2^(4/9)]^2 = 2^(4/9 * 2) = 2^(8/9)
so the area of square is 2^(8/9) sq. inches.

Answer:

384 cm²

Step-by-step explanation:

Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.

$\boxed{area \: of \: triangle = \frac{1}{2} \times base \times height }$

Area of a triangular face

= ½ ×12 ×10

= 60 cm²

$\boxed{area \: of \: square = side \times side}$

Base area of pyramid

= 12 ×12

= 144 cm²

∴ Surface area of pyramid

= 4(60) +144

= 240 +144

= 384 cm²
