Question 624219: what is the surface area of a room, width 124in. length 134 in. height 92in? I have this formula A= 2(wh + lw + lh) I have A= 2(216 + 258 + 266)
A = 2 (740)
A = 1480
I just want to know if the formula is correct, and if my answer is correct.

+A+=++2%28+w%2Ah+%2B+l%2Aw+%2B+l%2Ah+%29+ is correct
+w+=+124+
+l+=+134+
+h+=+92+
+A+=+2%2A%28+124%2A92+%2B+124%2A134+%2B+134%2A92+%29+
+A+=+2%2A%28+11408+%2B+16616+%2B+12328+%29+
+A+=+2%2A%28+40352+%29+
+A+=+80704+
The surface area is 80,704 in2
or, +80704%2F%2812%5E2%29+=+560.444+ square ft
