1. Use the figure below to answer the questions.

a. What is the name of the 3D shape?

b. What is the formula for total surface area for this shape?

c. What is the surface area of the figure?

A = 144 cm^2

Step-by-step explanation:

a.

The 3D shape shown in the image is a prism, known because it has two parallel faces called bases (the front and back triangles) and the other faces being parallelograms.

b.

To compute the total surface area, we must add the area of the five faces of the shape.

For the bases:

For the upper face

Where z is the hypotenuse of the triangle and w is the depth of the prism.

For the face-down surface

For the right face

The total area is

c.
