There are 14 times in the table.  Add up all 14 times, and divide the sum by 14.  The result is the "mean 100-meter sprint time," assuming that you've rounded this off to the nearest tenth of a second.

A large wooden box, as shown, has a volume of 4352 ft3. The box is a right square prism with a base with sides that each measure
notsponge [240]
<h2>Volume of a Prism</h2>

To find the volume of a prism, we can use the following formula:

V=base\hspace{3}area*height

Although this formula is typically used to find the volume of a prism, we can also use it to find the base area or height, as long as we re-arrange it accordingly.

For a rectangular prism, the base area is solved using the following formula:

A=lw ⇒ where <em>l</em> is the length and <em>w</em> is the width

<h2>Solving the Question</h2>

We're given:

  • V = 4352 ft³
  • <em>l</em> = 16 ft
  • <em>w</em> = 16 ft
  • We need to solve for the height of the box.

First, find the base area:

A=lw\\A=16^2\\A=256

Therefore, the base area is equal to 256 ft².

Now, modify the volume formula to isolate the height:

V=base\hspace{3}area*height

⇒ Divide both sides by the base area:

\dfrac{V}{base\hspace{3}area}=\dfrac{base\hspace{3}area*height}{base\hspace{3}area}\\\\\dfrac{V}{base\hspace{3}area}=height\\\\height=\dfrac{V}{base\hspace{3}area}

⇒ Plug in the given values:

height=\dfrac{4352}{256}\\\\height=17

Therefore, the height of the box is 17 ft.

<h2>Answer</h2>

The height of the box is 17 ft.

The radius of a circle is 4.3 inches. Using the formula A ≈ 3r2, what is the approximate area of the circle?
xz_007 [3.2K]
Please, use the symbol " ^ " to denote exponentiation.  At first I had no idea what you meant by 3r2.  

You are using the approx. formula A = 3 r^2 to find the area.
The given radius is 4.3 inches.   Subst. this value for r in the above equation.
Find A (keeping in mind that it's an approximation).
