Iam trying to find the surface area if you do not have the work that goes along with the problem don’t answer (the number that you can not see to clear is 7cm)

To find the surface area, you will need to find the area of all 6 surfaces (all the faces).  They are all rectangles and many of them are congruent!!  To find the area of each rectangle, use the formula A = lw. The front and back have the same area (7 x 6 = 42 square cm), the two sides have an area of 36 square cm (6 x 6 = 36), and the top and bottom have an area of 49 square cm (7 x 7 = 49).  Add the areas of all 6 sides together (42 + 42 + 36 + 36 + 49 +49  = 254 square cm - don't forget you label).  Another way would be to take 2 x 42 + 2 x 36 + 2 x 49.

Where is the diagram
