Explain how you can find the side length of a rectangular prism if you are given the volume and the 2 other measurements. Does this process change if one of the measurements is a fraction?

Sagot :

Answer:

The volume of a rectangular prism can be calculated by the formula:

  • Volume of a rectangular prism = length * width * height

If the exercise give us the volume and the two other measurements (width and height), we must simplify the length from the formula showed (remember when a value is multiplying in a side to the equal sign, go to the other side to divide):

  • (Volume of a rectangular prism) / (width * height) = length

Or, in other form:

  • [tex]length=\frac{volume}{width*height}[/tex]

At last, the proccess change only a little if one is a fraction, in that case, you should just multiply or divide with that fraction.

Step-by-step explanation:

We're gonna take measurements for the volume, width and height to solve a hypothetical exercise:

  • Volume = 240 [tex]in^{3}[/tex]
  • Width = 4 in
  • Height = 12 in

We use the formula in the answer:

  • [tex]length=\frac{volume}{width*height}[/tex]

Replacing the data we obtain:

  • [tex]length=\frac{240in^{3} }{4 in *12in }[/tex]
  • [tex]length=\frac{240in^{3} }{48in^{2} }[/tex]
  • [tex]length=[/tex] 5 inches

Now, we're gonna make the a hypothetical exercise where a measurement is a fraction, we can select anyone, in this case will be the width:

  • Volume = 48 [tex]in^{3}[/tex]
  • Width = 8/3 in
  • Height = 6 in

We use the same formula and replace again:

[tex]length=\frac{volume}{width*height}[/tex]

  • [tex]length=\frac{48in^{3} }{\frac{8}{3}in *6 in}[/tex]
  • [tex]length=\frac{48in^{3} }{16in^{2} }[/tex]
  • [tex]length=[/tex] 3 inches

As you can see, the process does't change much using fractions, you must only know the correct form to operate these.
