Explanation:

Step1: Identify the formula for surface area of rectangular solid

The formula for the surface area of a rectangular solid is $SA = 2LW+2LH + 2WH$, where $L = 15$ m, $W=6$ m, and $H = 13$ m.

Step2: Calculate the surface area

\[

$$\begin{align*} SA&=2\times15\times6+2\times15\times13+2\times6\times13\\ &=180 + 390+156\\ &=726 \end{align*}$$

\]
So the surface - area is 726 square meters.

Step3: Identify the formula for volume of rectangular solid

The formula for the volume of a rectangular solid is $V = LWH$, where $L = 15$ m, $W = 6$ m, and $H=13$ m. First, calculate the volume in cubic meters: $V=15\times6\times13=1170$ m³.

Step4: Convert volume from cubic meters to cubic centimeters

Since 1 m³ = 1000000 cm³, then $V=1170\times1000000 = 1170000000$ cm³.

Answer:

Surface Area = 726 square meters
Volume = 1170000000 cubic centimeters
