Answer:
2257 pounds
Step-by-step explanation:
First, get the volume of each and since density is the same, we shall use the density to get the other mass
First volume
Volume=lwh where l is length, w is width and h is height.
Substituting with the given figures
Volume=4*9*168=6048
Density
Density is mass per unit volume
D=m/v
Mass is given as 7900 pounds
Density is 7900/6048=1.3062169312169
Volume of second box
V=2*6*144=1728
Mass is product of volume and density hence 1.3062169312169*1728=2257.1428571428 pounds
Rounded off as 2257 pounds
