Find the area of the two triangular bases
Use the formula for the triangle area: 1/2 × base × height
Multiply that triangle area by 2
Find the area of each rectangular side
Use the formula for rectangle area: length × width
Add the areas of all three rectangles
Add the total area of the two triangles and the three rectangles
Use the formula: Surface Area = 2B + Ph
Let B = area of one triangular base
Let P = perimeter of the triangular base
Let h = length of the prism
Calculate the final surface area in square units
