A cube with 3-inch edges is to be constructed from 27 smaller cubes with 1-inch edges. Twenty-one of the cubes are colored red a
Diano4ka-milaya [45]
The volume of the larger cube is 3*3*3, which is 27.
The volume of the smaller cubes is 1*1*1, which is 1.
27/1=27
That means all cubes will be used, so only the placement of the cubes matter.
The center of the cube will show no sides,
The center of the face will show 1 side, which has a surface area of 1sq.in.
Since there are 6 white cubes and 6 faces with 6 face centers, and only one cube center, there will be 5 cubes on the center of the faces and 1 in the cube center.

This means there will be 0 faces of 1 cube and 1 faces shown for the rest of the cubes. Since each face is 1sq.un., the rest is math

(0*1)+((1*1)5)
(0)+(1*5)
0+5
5sq.un. of the cube is white.

a=The fraction of surface area showing
b=Surface area of large cube

b=3*3*number of sides on cube(6)

5*a=b
5*a=54
a=54/5

Your answer is 54/5.

Answer?? multiplying monomials
galben [10]

Answer:

-9y^8

Step-by-step explanation:

-3y^4 * 3y^4

Multiply the coefficients

-3*3 = -9

Add the exponents since the base is the same

y^4 * y^4 = y^(4+4) = y^8

Put them back together

-9y^8

The graphs of 4x + 12y + 8 and y = mx + 5 are perpendicular. What is the value of m?
gavmur [86]

Answer:

m=3

Step-by-step explanation:

To get a perpendicular equation to another equation, the slope must be the reciprocal of it.

First, you need to isolate the y variable so you can identify the slope.

12y = 8 - 4x

Divide both sides by 12 (and for me I like to keep x close to y).

y=-1/3x+2/3

Now that we have converted it to y=mx+b, we can compare. The reciprocal of 1/3 is 3.

so m = 3.
