First fine the area of the two sides length and height

Step-by-step explanation:

2lw+2lh+2wh

That right this is like height length and width

Find the area of two sides (Length*Height) * 2 sides.

Find the area of adjacent sides (Width*Height) * 2 sides.

Find the area of ends (Length*Width) * 2 ends.

Add the three areas together to find the surface area.
