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

1 answer:

3 0

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.

Answer:

a = 15/4

Step-by-step explanation:

tan 60 = y/a

√3 = y/a

y = √3a

tan 30 = y/b

1/√3 = y / b

y = b/√3

√3 a = b/√3

3a = b

a+b = 15

a + 3a = 15

4a = 15

a = 15 / 4

Since the triangle is equilateral (you can tell by the tick on each side), all angles have the same measure as well.

The angles of a triangle sum up to 180 degress, so three equal angles must measure 60 degrees each.

So, in particular, we have

7x + 4 = 60 7x = 56 x = 8
