To calculate the surface area of the rectangular prism in the given image, we use the surface area formula for a rectangular prism:

$\text{Surface Area} = 2(lw + lh + wh)$

Where:

• $l = 9$ meters (length),
• $w = 4$ meters (width),
• $h = 3$ meters (height).

Step-by-Step Calculation:

1. Find the area of each pair of opposite faces:

   • Two $l \times w$ faces: $9 \times 4 = 36$ square meters.
   • Two $l \times h$ faces: $9 \times 3 = 27$ square meters.
   • Two $w \times h$ faces: $4 \times 3 = 12$ square meters.

2. Sum of the areas of all six faces: $2(36 + 27 + 12)$

3. Simplify: $36 + 27 + 12 = 75$ $2 \times 75 = 150 \, \text{square meters}.$

Final Answer:

The surface area of the rectangular prism is:

$\boxed{150 \, \text{square meters}}.$

Tip: Surface area grows faster than volume as dimensions increase, which is important for things like packaging and construction!
