Quizplus · Accepted Answer

There are 2 layers, each with 6 rows of 15 candy bars. We can find the total number of candy bars by multiplying the number of rows by the number of candy bars in each row and then multiplying that by the number of layers. 
So, total number of candy bars = 2 x 6 x 15 = 180. Therefore, the best choice is C). There are 2 layers with 6 rows and 15 candy bars in each row, so the total number of candy bars in one layer is 6 x 15 = 90. Multiply this by 2 layers to get a total of 180 candy bars in the case. Therefore, the best choice is C).
