THIS IS THE CORRECT ANSWER...
EXPLANATION:
THERE ARE SIX LATERAL FACES:
TWO FACES OF DIMENSION : 5 * 8
TWO FACES OF DIMENSION : 5 * 13
TWO FACES OF DIMENSION : 8 * 13
SURFACE AREA OF ABOVE FACES WOULD BE ((5X8)+(5X13)+(8X13)) x 2 = 418
Dear Jiju.... If u take one side surface, u cant take that portion on other side.. u have to leave that portion
