Answer 1

12+6x5= 45 because are of a trapezium is a+b/2x5 then x 45 by 16 = 720

Answer 2

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
