The equation for the area of a triangle is A= b*h /2. So, plug in your known variables, and you get 270in^2= b*30 /2. First you multiply by 2 to cancel out the division for 2, which gets you 540= b* 30. To get "b" by itself, divide both sides by 30, giving you 18=b.

To check this, plug in your new known variable, as 270= 18* 30 /2. This will equal as 270=270, confirming 18in as the correct measurement.

Ryan finds that the volume of a rectangular box is 4080 cubic centimeters. The length of the box is 15 centimeters and the heigh

Dafna11 [192]

The colume of a rectangular box (rectangular prism) is given by the next formula:

$V=l\cdot w\cdot h$

As you need to fidn the width, solve w in that formula:

$w=\frac{V}{l\cdot h}$

Use the given measures and calculate the width:

$\begin{gathered} w=\frac{4080cm^3}{15\operatorname{cm}\cdot17\operatorname{cm}} \\ \\ =\frac{4080cm^3}{255cm^2} \\ \\ =16\operatorname{cm} \end{gathered}$ Then, the width of the rectangular box is 16 centimeters
