The difference is that evaluating an expression for a given value is an example of let’s say In a example, the variable x is equal to 6 since 6 + 6 = 12. So it means that they are giving you the input already. SOLVING an equation is working backwards, to undo everything that has been done to the input. So you have to do the equation in order to find your answer.

What is the volume of this rectangular prism?

sergiy2304 [10]

Answer:

$V =\frac{12}{5}\ cm^3$

Step-by-step explanation:

<u>The Volume of Rectangular Prism</u>

Given a rectangular prism of dimensions W, L, and H, its volume is the product of the three dimensions:

V = WLH

The figure shows the dimensions:

L=3 cm

$W=\frac{4}{3}\ cm$

$H=\frac{3}{5}\ cm$

Thus, the volume is:

$V =3*\frac{4}{3}*\frac{3}{5}\ cm^3$

$V =\frac{36}{15}\ cm^3$

Simplifying:

$\boxed{V =\frac{12}{5}\ cm^3}$
