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

Step-by-step explanation:

First, find the volume:

V =  Length · width · height

  $= (16)\bigg(\dfrac{6+12}{2}\bigg)(5)\\\\= (16)(9)(5)\\\\= 720$

Next, find the mass using the density formula $p = \dfrac{m}{V}$

mass (m) = density (p) · volume (v)

$m=\dfrac{19.3\ g}{cm^3}\times 720\ cm^3\\\\.\quad=13,896\ g$

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

13,896 g = 13.896 kg
