Answer: you will have 120 cubes
V = lwh
You're given length, width, and height of the prism, so:
V = (5/3) * (4/3) * (2)
V = 40/9 cm³
Now, you need to find the volume of each cube that'll be filling the prism. Since it's a cube, the length, width, and height are the same.
Therefore the volume is simply:
V = (1/3)³
V = 1/27cm³
To find how many cubes will fill the prism now, divide (40/9) by (1/27).
This results in 120 cubes being able to fill the prism.
Step-by-step explanation:
Basically, you try to find 2 numbers that divide to 3/2. So, using trial and error, plug in numbers for x in this expression: x/24=3/2, and solve to find the number that makes it true. You end up getting 36/24=3/2. Hope that helps! :)

Step-by-step explanation:
<u>Step 1: Define</u>
c - 9x
c = 6
x = -7
<u>Step 2: Evaluate</u>
- Substitute: 6 - 9(-7)
- Multiply: 6 + 63
- Add: 69
''Decreased'' means subtract and ''times'' means multiplication so the algebraic expression should be 15 - 2 * p.
