You can put this solution on YOUR website!
since you have square pyramid (and assume a = 4 in, b = 5 in) which is a container that may not have a top, means you will not need the area of the base a%5E2=4%5E2=16
so, you will calculate lateral area:
L+=+4+%2A+%281%2F2%29a%2As+=+2a%2As+
L+=+4+%2A+%281%2F2%29%2A4in%2A5in
L+=++2%2A4%2A5in%5E2
L+=+highlight%2840in%5E2%29
if you include base area of a square pyramid (square):
+B+=+a%5E2
+B+=+%284in%29%5E2
+B+=+16in%5E2

you will have:
Total Surface Area of a square pyramid:
A+=+L+%2B+B+=40in%5E2%2B16in%5E2
+highlight%28A+=56in%5E2%29
