The given pyramid's total surface area is 3. 24.0 square feet.

Step-by-step explanation:

Step 1:

To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.

There are 3 triangles and 1 square in the figure.

Step 2:

All the triangles are similar.

The surface area of a triangle = \frac{1}{2} (baselength)(height).

The similar triangles have a base length of 3 feet and a height of 2.5 feet.

The surface area of 1 similar triangle = \frac{1}{2} (3)(2.5)= 3.75 square feet.

The surface area for all the similar triangles = 3.75 (4) = 15 square feet.

Step 3:

The surface area of a square is the square of its side length. The square has a side length of 3 feet.

The surface area of the square = a^{2} = 3^{2} =9 square feet.

Step 4:

To calculate the total surface area we sum up all the individual surface area.

The total surface area = 15 + 9 = 24 square feet which is the third option.
