I need help with math

kenny6666 [7]

Answer:

264 inches

Step-by-step explanation:

Let's start with the top cube.

We can figure out the volume by multiplying the length, width, and height. So for this problem, it will be 4x5x6. 4x5 is obviously 20, and 6x20 is 120. So the top cube is 120 in.

The bottom cube has the dimensions 4x6x6. I know 6x6 is 36. So 36x4 is 144.

So 120+144=264

Let me know if you have any questions!

What is the measure of the sum of all angles in a regular dodecagon (12 sides)? What is the measure of one of its interiors angl

lana66690 [7]

Answer:

Part a) The measure of the sum of all angles in a regular dodecagon is equal to 1,800 degrees

Part b) The measure of one of its interiors angles is 150 degrees

Part c) The measure of one of its exterior angles is 30 degrees

Step-by-step explanation:

Part a) What is the measure of the sum of all angles in a regular dodecagon (12 sides)

we know that

The formula to calculate the sum of the interior angles in a regular polygon is equal to

$S=(n-2)180^o$

where

n is the number of sides of regular polygon

In this problem a regular dodecagon has n=12 sides

substitute

$S=(12-2)180^o$

$S=(10)180^o$

$S=1,800^o$

Part b) What is the measure of one of its interiors angles?

To find out the measure of one of its interior angles, divide the sum of all angles by the number of sides

$1,800^o/12=150^o$

Part c) What is the measure of one of its exterior angles?

we know that

The sum of one interior angle and its corresponding exterior angle must be equal to 180 degrees

Let

x ---> the measure of one exterior angle

$150^o+x=180^o$

solve for x

$x=180^o-150^o$

$x=30^o$
