The volume corresponds to the measure of the space occupied by a body. From the given dimensions we can intuit that we are looking to find the Volume of an Cuboid, that is, an orthogonal rectangular prism, whose faces form straight dihedral angles.
Mathematically the volume of this body is given as

Where,
L = Length
W = Width
H = High


Note: The value given for the height was in centimeters, so it was transformed to meters.
Answer : The volume of engine in cubic inches is, 
Explanation :
As we are given that the volume of engine is, 7.0 liters. Now we have to calculate the volume of engine in cubic inches.
Conversion used :

So, 

or,


As,

So,

Thu, the volume of engine in cubic inches is, 
The tendency for two masses alone in the universe to drift together is a result of gravitational pull.
Answer:
Explanation:
the momentum of a body is defined as the product of mass of body and the velocity f the body.
P = m x v
Where, m is the mass and v be the velocity of the body.
it is a vector quantity and its unit is newton second.
When the velocity of the object is zero, the momentum is also zero.
Newtons' first law states that the body is at rest or in motion , it remains at rest or in motion until and unless an external force is not applied on the body.
So, When a body is at rest it remains at rest.
