A rectangular prism is 6 inches long, 3 inches wide, and 2 inches high. What is its surface area?

Serga [27]

We can label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, because it has '6' faces and to find the surface area put the values in the formula:

SA=2(6)(3)+2(6)(2)+2(2)(3)
SA=36+24+12
SA=72

A recipe for a cake instructs you to bake it at 220° C for 45 minutes. How many degrees Fahrenheit is this?

sergiy2304 [10]

This is an exercise on Thermometric scales.

We have as data:

T = 220 °C
T = °F ??

We apply the following formula:

$\large\displaystyle\text{$\begin{gathered}\sf ^{\circ}F=\frac{9}{5}\ ^{\circ}C+32 \end{gathered}$}$

We substitute data in the formula:

$\large\displaystyle\text{$\begin{gathered}\sf ^{\circ}F=\frac{9}{5}\times220+32 \end{gathered}$}$

First multiply 9 x 220, then the result of this division is divided by 5.

$\large\displaystyle\text{$\begin{gathered}\sf =396+32 \ \ \to \ \ [Add] \end{gathered}$}$

$\boxed{\large\displaystyle\text{$\begin{gathered}\sf =428 \ ^{\circ}F \end{gathered}$}}$

Therefore the cake recipe that should be baked at 220 °C for 45 minutes, on the Fahrenteir scale is 428 °F. Which indicates that it will be very hot.
