We can use a net to calculate the surface area of the rectangular prism. Let's see a net!
Every polygon in the net is a rectangle. Let's calculate the area of each rectangle separately and add them up!
Face
Length l
Width w
Area=l * w
Bottom
9
6
9* 6=54m^2
Top
9
6
9* 6=54m^2
Side
5
6
5* 6=30m^2
Side

6
5* 6=30m^2
Front

5
9* 5=45m^2
Back

5
9* 5=45m^2
We now have all the information that we need to find the total surface area of the rectangular prism. Let's add the areas of the faces to get the whole area!
Total Surface Area
54+ 54+ 30+ 30+ 45+ 45=258m^2
The total surface area is 258 square meters.
