Someone help me with my math homework pleaseee. Find the volumes of the pyramids and the height is 7cm for the first one.
gregori [183]
\bf \textit{volume of a pyramid}\\\\
V=\cfrac{1}{3}Bh\qquad 
\begin{cases}
B=\textit{area of the base}\\
h=height
\end{cases}

now, the first one, on the far-left.... can't see the height.. but I gather you do, now as far as its Base area, well, the bottom is just a 12x12 square, so the area of its base is just 12*12


now, the middle pyramid, has a height of 6, the base is also a square, 8x8, so the Base area is just 8*8

now the last one on the far-right

has a height of 8, the Base is a Hexagon, with sides of 6

\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}ns^2cot\left( \frac{180}{n} \right)\qquad 
\begin{cases}
n=\textit{number of sides}\\
s=\textit{length of one side}\\
\frac{180}{n}=\textit{angle in degrees}\\
----------\\
n=6\\
s=6
\end{cases}\\\\\\ A=\cfrac{1}{4}\cdot 6\cdot 6^2\cdot cot\left( \frac{180}{6} \right)

Together,two boxes of spices weigh 4 pounds 8 ounces. Each pound is worth $400. How much are the boxes worth in all.
Zanzabum

The total worth of the 4 pounds and 8 ounces of box is $1800

<h3>Total cost</h3>

Weight of the boxes:

  • 4 pounds
  • 8 ounces
  • Cost of each pound = $400

Convert ounces to pounds:

8 ounces to pounds = 0.5 pounds

Total cost of the boxes = 4 pounds (400) + 0.5 pounds (400)

= 1600 + 200

= $1,800
