There are 12 cookies in a container. There are 12 containers packed in a box for shipping. There are 12 boxes loaded onto a ship
mamaluj [8]

Option A

Total number of cookies on a shipping truck when 12 boxes are loaded is 1728.

<u>Solution:</u>

Need to determine correct option of total number of cookies on the truck

From given information

Number of cookies in 1 container = 12  

Number of container in 1 box = 12  

So number of cookies in 1 box = number of cookies in 12 container  

\Rightarrow \text { Number of cookies in } 1 \text { box }=\text { number of cookies in } 1 \text { container } \times 12

=12 \times 12=144

Number of boxes loaded onto 1 shipping truck = 12  

So Number of cookies onto 1 shipping truck = number of cookies in 12 boxes

\Rightarrow \text { Number of cookies onto } 1 \text { shipping truck }=\text { number of cookies in } 1 \text { box } \times 12

=144 \times 12=1728

Hence total number of cookies on a shipping truch when 12 boxes are loaded is 1728. Thus option A is correct

Delicious77 [7]
If you would like to know 55 percent of what number is 495, you can calculate this using the following steps:

55% of what number = 495
55% * x = 495
55/100 * x = 495
x = 495 * 100/55
x = 900

The number you are looking for is 900.
