A rectangular prism is packed with cubes that measure 1/4 inch on each side. What is the volume, in cubic inches, of the rectang
Vladimir79 [104]

V = n X V(cube)

<u>Explanation:</u>

Given:

Side of the cube,a = \frac{1}{4}

Volume of the cube = a³

So, the volume of the cube, V is

V(cube) = (\frac{1}{4})^3

V(cube) = \frac{1}{64}

Let the number of cubes be n

Let V be the volume of the rectangular prism

Volume of rectangular prism = number of cubes X volume of cubes

V = n X V(cube)

If the number of cubes are known then substitute the value in the above given formula.

PBR - (pls give the formula and full solution)
Ray Of Light [21]

Answer:

I'm in class so I'll answer what I can!

1. okay so 25%=40 so to get to 100% we need to multiply 25% by 4 and so we so the same with the number 40x4 equals 160cm

2. so 8k from 20k think of 10k as 50% so it's around 5 per 1k so 8k would be 40% and so 60% would have been spent

3. (I might edit this one later I'm in class :(()

4. so 200cm last year and 240cm this year so it gre by 40cm so it'd be 20% (200=100% so that means it's twice as much as what the % would be!)

5. so 60 is 40% so 30 is 20% so just add up from there 20 x 5 = 100% so 30 x 5 = 150km

After taking off from the landing pad, a helicopter flies 3 miles west, then 2 miles southeast. How far is the helicopter from t
pashok25 [27]

Answer:

When the plane makes its turn to fly southeast, it makes a 45º angle at point a, making angle abc also equal to 45º.  

Line ab is the 2 miles southeast the plane flies.

Line ac = line cb

sine (45º) = opposite / hypotenuse = cb / 2

.70711 = cb / 2

cb = 1.41422  miles = line ac

Line cs = 3 - 1.41422 = 1.58578

Line x^2 = cs^2 + cb^2

Line x^2 = 2.5146982084  + 2.0000182084

Line x^2 = 4.5147

Line x = 2.1248
