What is the surface area of the square pyramid represented by the net?

The surface area of the pyramid is 39 square feet.

Step-by-step explanation:

The surface area of the square is composed of 4 isosceles triangles and a square.

The area of the isosceles triangle with  height and base length is given by

For the pyramid, the isosceles triangle has height and base length ; therefore, its area is

And therefore, the total area of the 4 triangular sides is

.

The area  of the square base of the pyramid is the square of its side length:

Therefore, the total surface area of the square pyramid is :

Therefore, the surface area of the pyramid represented by the net is 39 square feet.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
