Answer : Weight of the truck = 9408 N
Explanation :
Given that,
Length = 6.0 m
Width = 4.0 m
Depth = 4.00 cm
we know that,
weight of the truck = weight of the displaced water
weight of the truck = 
we know that,
density 
mass = density X volume
weight of the truck = 
Now, the volume = length X width X depth


Weight of the truck 
Weight of the truck = 
Weight of the truck = 9408 N
Hence, this is the required solution.
The oceanic crust slides under the continental crust due to the differences in their densities. The continental rust is more felsic (contains more silica) which makes it lighter than the oceanic crust which is more mafic (contains more fe and mg)<span />
