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:
a) 4830
b) 5120
c) 6420
d) 8960
Answer: b
Explanation: 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) m3
= 5120 m3
