Volume = l*w*h = (18.1 cm)(19.2 cm)(20.3 cm) = 7,054 cm^3.
Folds and faults are difficult to identify because they occur in the interior of rocks and also due to the dense nature of the materials.
<h3>What are faults and folds?</h3>
Faults are lines of weakness are present in materials dues to uneven positioning of the particles of the material.
Folds occurs when infolds occur in materials.
Faults and folds usually occur in rocks.
Folds and faults are difficult to identify because they occur internally and also due to the dense nature of the materials.

The only scalar quantity is a. 35 m
Explanation:
In physics, there are two types of quantities:
- Scalar: a scalar quantiy is a quantity having only a magnitude, so it is just a number followed by a unit. Examples of scalar quantities in physics are:
Speed
Energy
Distance
Time
- Vector: a vector quantity is quantity having both a magnitude and a direction. Examples of vector quantities in physics are:
Velocity
Force
Acceleration
Displacement
Let's now analyze each given option, to evaluate if it is a scalar or a vector:
a. 35m --> it is only a unit (no direction), so it is a scalar
b. 20 m to the right --> it has a direction, so it is a vector
c. 30 m to the North --> it has a direction, so it is a vector
So, the only correct option is a).
