Answer:
44 square units
Step-by-step explanation:
To find the surface area of a rectangular prism, we need to add up the areas of all six of its faces.
For this rectangular prism, we have:
The top and bottom faces are both rectangles that are 4 units wide and 2 units long, so their combined area is 2 * 4 + 2 * 4 = 16 square units.
The front and back faces are both rectangles that are 4 units high and 2 units long, so their combined area is 2 * 4 + 2 * 2 = 12 square units.
The left and right faces are both rectangles that are 4 units high and 4 units wide, so their combined area is 2 * 4 + 2 * 4 = 16 square units.
To find the total surface area, we just need to add up all six of these areas:
16 + 12 + 16 = 44 square units
So the surface area of this rectangular prism is 44 square units.
