1) Cross-sectional area
2) Volume
3) Mass
Cross-sectional area = 1/2(a + b)h
1/2( 6 + 10 )4
1/2(16 x 4)
1/2 x 64
64/2 = 32cm^2
Volume = Cross-sectional area x Length
Volume = 32 x 14
Volume = 448 cm^3
Density = Mass/Volume
Density x Volume = Mass
Mass = Density x Volume
Mass = 19.3 x 448
Mass = 8646.4 grams
It asks for kilograms, so:
8646.4/1000 = 8.6464 kg
