a prism is filled with cubes that have edge lengths of 1/4 in. how many cubes are needed to fill the rectangular prism

Advocard [28]

This is going to require a good bit of division. I am going to turn the mixed fractions into improper fractions. Remember that to divide fractions, you take the 2nd fraction, flip it, and multiply.

First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10

Next, 3/(1/4) = 3(4) = 12

Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13

This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.

Please help. For each box, just number them. Example: The top box is 1, the middle box is 2, and the third box is 3.

Feliz [49]

Answer:

box 1=4

20/5= 4 (if you divide the others by x and y they equal 4)

box 2=512

if every square mile has 4 squirrels. then you multiply 128×4=512

box 3=81 because you divide 324/4=81
