The total surface area of a rectangular prism is found by adding up the areas of all its faces using the formula Total Surface Area = 2lw + 2lh + 2wh.
The total surface area of a rectangular prism can be found by adding up the areas of all its faces.
For example, let's say the dimensions of the rectangular prism are length (l), width (w), and height (h). The formula for the total surface area is:
Total Surface Area = 2lw + 2lh + 2wh
In this formula, we calculate the area of the two length-width faces (2lw), the two length-height faces (2lh), and the two width-height faces (2wh), and add them all together.
To find the correct answer, substitute the given dimensions of the rectangular prism into the formula and evaluate it to determine which option matches the result.
