Add them together!
Add together the areas of all 6 sides.
Partition it into simple shapes and work out their areas. Then add together all the components.
You have to find the areas of each individual triangle's area and add them all up together.
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.

Find the areas of the rectangles and triangles. Add them together.
Take the area (Length x Width) of every side and add all of the areas together.
to find the surface area you have to first find the area of each part then add the areas together.
You need to break down the composite figure into simpler shapes whose areas you can calculate using appropriate formule and then add together the areas of all the individual bits.
For the area you just multiply base by height and divide by 2. For the perimeter you just add all the lengths together
To find the perimeter and areas of complex shape without a grid you should divide the shape into simple shapes and find the area of each shape alone and then add up the areas all together to get the area of the whole shape. Example: If there is a shape that can be divided into 2 triangles and 1 rectangle then you will find the area of each triangle alone and then the area of the rectangle then add up all the areas together.
