The combined weight of all the samples can simply be calculated by the arithmetic sum of all the individual weights of each sample.
The total <em><u>combined weight</u></em><em> </em>of all the samples is "114.22 lb".
Adding the individual weights of each sample we get:
Combined weight = Weight of sample 1 + Weight of sample 2 + Weight of sample 3
Combined Weight = 31.2 lb + 38.02 lb + 45 lb
<u>Combined Weight = 114.22 lb</u>

Answer:
1. Density = 1200[kg/m^3]; 2. Volume= 0.005775[m^3], mass= 15.59[kg]
Explanation:
1. We know that the density is defined by the following expression.
2. First we need to convert the units to meters.
wide = 35[cm] = 35/100 = 0.35[m]
long = 11 [dm] = 11 decimeters = 11/10 = 1.1[m]
Thick = 15[mm] = 15/1000 = 0.015[m]
Now we can find the density using the expression for the density.
