Calculate the surface area and volume of a trapezoidal prism with given dimensions.

Here are the calculations for the surface area and volume of the given shapes.

Shape 1: Trapezoidal Prism
The first shape is a prism with a trapezoidal base.
The dimensions of the trapezoidal base are:

• Height ($h_t$) = $5 \text{ cm}$
• Bottom base ($b_1$) = $6 \text{ cm}$
• Top base ($b_2$) = $8 \text{ cm}$ The length of the prism ($L$) = $12 \text{ cm}$.

Step 1: Calculate the area of the trapezoidal base.
The formula for the area of a trapezoid is $A = \frac{1}{
