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 8 m, the volume of the box (in m3) is Choose the correct choice.
A) 3220 B) 4830 C) 5120 D) 6420 E) none

Rationale: "solution clearly , l = ( 48 - 16 ) m = 32 m ‹ = › b = ( 36 - 16 ) m = 20 m , ‹ = › h = 8 m . . volume of the box = ( 32 x 20 x 8 ) m 3 = 5120 m 3 . answer c"
Answer: C
