Answer:

132 square millimeters

Step-by-step explanation:

THe <u>lateral area</u> of a rectangular prism is the side areas. That is

all 4 sides of the rectangular prism (that are rectangles each).

So, we find each side area and add them up.

The area of a rectangle is:

Area = length * width

The left side (in gray) is 9 mm x 3mm, so area:

area = 9 * 3 = 27

The right side rectangle is same, so that would have an area of:

area = 9 * 3 = 27

Now, the front side's measurement is 3 x 13, so the area is:

Area = 3 * 13 = 39

THe back is same, so the area would be:

Area = 3 * 13 = 39

<u>Total Surface Area = 27 + 27 + 39 + 39 = 132 square millimeters</u>

Beau's recipe fro granola bars calls for 3 1/2 cups of oatmeal. He only has 1/6 scoop. How many scoops of oatmeal will he need t

natulia [17]

$\boxed{21}$ scoops of oatmeal will he need to complete the recipe.

Further explanation:

Given:

Beau's recipe from granola bars calls for $3\dfrac{1}{2}$ cups of oatmeal.

He only is $\dfrac{1}{6}$ scoop.

Explanation:

The cups of oatmeal called for the recipe is $3\dfrac{1}{2}.$

Solve the improper fraction $3\dfrac{1}{2}.$

$\begin{aligned}{\text{Fraction}}&=\frac{{2 \times 3 + 1}}{2}\\&=\frac{{6 + 1}}{2}\\&=\frac{7}{2}\\\end{aligned}$

The Beau has $\dfrac{1}{6}{\text{ scoop}}.$

The number of scoops required to complete the recipe can be obtained as follows,

$\begin{aligned}N&=\frac{{{\text{total cups of oatmeal}}}}{{{\text{the fraction of scoop Beau has}}}}\\&=\frac{{\frac{7}{2}}}{{\frac{1}{6}}}\\&= \frac{7}{2} \times6\\&=\frac{{42}}{2}\\&= 21\\\end{aligned}$

Number of scoops required to complete the oatmeal is $21{\text{ scoops}}.$

Therefore, $\boxed{21}$ scoops of oatmeal will he need to complete the recipe.
