# Surface Area of a Rectangular Prism

### By Taylor Jones

Surface Area - is the sum of all the **areas** of all the shapes that cover the **surface** of the object.

Formula - SA=2(lw+hl+hw)

Now I will show you an example that is already done!

SA= 2(lw+hl+hw)

SA= 2[11(5)+6(11)+6(5)]

SA= 2(55+66+30)

SA= 2(151)

SA= 202 cm²

Now lets try an example together!
