### Calculating Properties of a Prism

The image provided outlines several mathematical aspects of a prism. The diagram includes a trapezoidal base and annotations regarding lengths and angles.

#### Diagram Description
The diagram shows a three-dimensional prism with a trapezoidal base. The side lengths are labeled as follows:
- The top length of the trapezoid: \(9\) units
- The bottom length of the trapezoid: \(13\) units
- The height (altitude) within the trapezoid: A dashed line connecting the top and bottom sides forms an angle \(60^\circ\) with the bottom side

The prism's length (depth extending into the third dimension) is \(14\) units.

#### Key Properties to Calculate

**(a) Perimeter of the base, \(p\)**

To determine the perimeter of the trapezoidal base, sum the lengths of all its sides. Note, you may need to calculate the lengths of the non-parallel sides using trigonometric functions if necessary.

**(b) Area of the base, \(B\)**

The area of a trapezoid can be calculated using the formula:
\[ B = \frac{1}{2} \times (a + b) \times h \]
where \(a\) and \(b\) are the lengths of the two parallel sides, and \(h\) is the height.

**(c) Lateral area of the solid, \(L\)**

For the lateral area, identify and sum the areas of the rectangular sides of the prism. There are four rectangles corresponding to the depth and the sides of the trapezoid.

**(d) Surface area of the solid, \(T\)**

The total surface area includes both the lateral area and the areas of the two trapezoidal bases:
\[ T = L + 2B \]

**(e) Volume of the solid, \(V\)**

The volume of the prism is found by multiplying the area of the base by the length (depth) of the prism:
\[ V = B \times \text{length} \]

By understanding these properties and how to calculate them, you will gain a better grasp of geometric concepts related to prisms.

**Note:** The diagram must be analyzed to extract exact measurements, especially for non-parallel sides and height, which might require the use of trigonometric functions if not directly provided.
