Answer: 13.896 kg

Explanation:

First, find the volume:

V = Length · width · height


= (16)\bigg((6+12)/(2)\bigg)(5)\\\\= (16)(9)(5)\\\\= 720


Next, find the mass using the density formula
p = (m)/(V)

mass (m) = density (p) · volume (v)


m=(19.3\ g)/(cm^3)* 720\ cm^3\\\\.\quad=13,896\ g


Lastly, convert gram to kg by moving the decimal 3 places

13,896 g = 13.896 kg
