Surface area is easy but hard. i will give you the formula and an example.

Formula: 2xlxw+2xlxh+2xhxw.

l= length

w= width

h= height

now say h= 4 in, l= 12 in and w= 3.5 in. now you would do lxw or 12x3.5. then multiply the product by 2. then do lxh or 12x4. now multiply by 2. finally, do hxw or 4x3.5. now add all your answers to get the final sum.
It depends on what you are looking for the surface area of. If it's a rectangular shape, it's length times width.
