A rectangular metallic sheet with dimensions of 48 m x 36 m is used. To produce an open box, a square is sliced off from each of its corners. If the square's length is 8 m, the box's volume (in m3) is:
A. 4830
B. 5120
C. 6420
D. 8960
Answer:B
A rectangular metallic sheet with dimensions of 48 m x 36 m is used. To produce an open box, a square is sliced off from each of its corners. If the square's length is 8 m, the box's volume (in m3) is:
A. 4830 B. 5120 C. 6420 D. 8960
Explanation: Clearly, l = (48 - 16)m = 32 m, and l = (48 - 16)m = 32 m.(36 -16)m = 20 m, b = (36 -16)m =h = 8 metres=(32 × 20 x 8) m3 = 5120 m3 is the volume of the box.
