To answer this question, it is enough to find the volume of a rectangular prism.
The volume of a rectangular prism is:
$V = Ab * h
$
Where,
Ab: base area
h: height
The area of the base is:
$Ab = w * l
$
Where,
w: width
l: long
We observe that the area of the base is a rectangle, therefore, the section parallel to the base is also a rectangle.
Answer:
The cross section cut parallel to the base of a right rectangular prism is:
Rectangle

Start by distributing the exponent to each of the terms in $(2u)^{3}$ . This will become $2^{3} u^{3}$ , and $2^{3} =8$ . Now, the expression is:

$\frac{2u^{3} v^{2} }{8u^{3} * u^{2} }$ .

We can now simplify the bottom to read: $8u^{5}$ because when multiplying variables raised to an exponent, we add the exponents. The expression now looks like:

$\frac{2u^{3} v^{2} }{8u^{5} }$

The 2/8 simplifies to 1/4:

$\frac{u^{3} v^{2} }{4u^{5} }$

Now, we have two u terms on the top and bottom. When dividing variables raised to an exponent, we subtract the exponents. However, since 3-5=-2, the term will be on the bottom to avoid the negative exponent. The final answer is:

$\frac{v^{2} }{4u^{2} }$
