Find the total surface area for the prism. Let the front and back faces be the prism bases.
Calculate the area of the base
To calculate the area of the base, you need to know the shape of the base. Prisms can have different base shapes such as rectangle, triangle, hexagon, etc.
For example, if the base is a rectangle, you would multiply the length of one side of the rectangle (base length) by the length of the adjacent side (base width) to find the area.
If the base is a triangle, you would use the formula for the area of a triangle, which is 1/2 multiplied by the base length multiplied by the height of the triangle.
If the base is a hexagon, you would need to know the specific formula for finding the area of a hexagon.
Once you have calculated the area of the base, you can use this value to find the total surface area of the prism.
