A metallic sheet is of rectangular shape with dimensions 48 m x 36 m. From each of its corners, a square is cut off so as to make an open box. If the length of the square is 6 m, the volume of the box (in m3) is:	Choose the correct choice:  A) 4830  B) 5184  C) 6420  D) 8960  E) 7960

Rationale: "clearly , l = ( 48 - 12 ) m = 36 m , b = ( 36 - 12 ) m = 24 m , h = 8 m . volume of the box = ( 36 x 24 x 12 ) m 3 = 5184 m 3 . answer : option b"
Answer: B
