Answer: 409.6 m^3
Explanation:
The volume of a rectangular prism is given by the formula V = l*w*h. The beam is considered a rectangular prism. We already know the area of the beam since it is specified as 16*16. This is also the l*w since area is l*w. So, V = 16*16*h. The height is given as 1.6 m. V = 16*16*1.6 = 409.6 m^3.
