(2b) A rectangular prism measures 2 &amp; 2/5 inches by 3 &amp; 1/5 inches by 2 inches. How many cubes with edge length 1/5 inch
erastova [34]

Answer:

1920 cubes.

Step-by-step explanation

Turn both the mix numbers into improper fractions.

2 2/5 = 12/5

3 1/5 = 16/5

Then you will turn 1/5 into its reciprocal and multiply both the improper fractions by it. You can just casually multiply 2 and 5.

12/5 * 5/1 = 12

16/5 * 5/1 = 16

2 * 5 = 10

Next you multiply all together to get 1920 cubes.

(I could be missing a step. I apologize if I did.)

A water cooler holds 1,284 ounces of water. How many more 6 ounce glasses than 12-ounce glasses can be filled from the cooler
yawa3891 [41]
Answer:
- The water cooler can hold 214 of the 6-oz glasses because 1284 / 6 = 214

- The water cooler can hold 107 of the 12-oz glasses because 1284 / 12 = 107

- Because it is asking how many more glasses, you would do 214 - 107 = 107.

- You could also say that the water cooler can hold twice as many 6-oz glasses than 12-oz glasses.

Hope that helps! :)
