The volume of the prism is a function of the cubes in it.
The volume of the prism is: <em>(b) 2 unit cubes and 9 smaller cubes of volume fraction 1 over 27 cubic inch each</em>
From the question, we have:
<em />
<em> --- number of cubes</em>
<em />
<em> --- the edge length of each cube</em>
<em />
So, the volume of a cube is:
This gives
The volume of the prism is then calculated as:
This gives
Rewrite as:
Split
Rewrite as:
The above equation means that, the volume of the prism is:
<em>(b) 2 unit cubes and 9 smaller cubes of volume fraction 1 over 27 cubic inch each
</em>

Answer:
The sum of 4 times a number and -3 added to 9 times the number is:
4x + (-3 + 9x)
Step-by-step explanation:
Determine what each of the words means
"the sum of" - you are going to be adding the following two numbers.
"4 times a number" - Let x be the number, so, 4x is the first number.
"and -3 added to" - again, it's going to be addition of this number and the following number.
"9 times the number" - let x be the number, so, 9x is the second number in the second addition.
Now that we know what it all means, put it together:
4x + (-3 + 9x)
I really hope this helps you =)
The sum of all angles (around the black dot) is 360°
All 5 angles (if you forget the red line) are the same; so each angle is 360°/5 = 72°
So Angle 1 is 72°
