How many 1/2 unit cubes can fit in a a prism with a volume of 6 cubic units

AlekseyPX

Answer:

48 cubes

Step-by-step explanation:

step 1

Find the volume of one 1/2 unit cube

The volume of the cube is given by

$V=b^3$

where

b is the length side of the cube

we have

$b=\frac{1}{2}\ units$

substitute

$V=(\frac{1}{2})^3$

$V=\frac{1}{8}\ units^3$

step 2

Divide the volume of the prism by the volume of one cube

$6:\frac{1}{8}=6(8)=48\ cubes$

<h3>Answer: Choice A $-4 \le x \le -2$ </h3>

Explanation:

Ask yourself this: "When is the graph completely horizontally flat?" The answer to this question is when x is between -4 and -2. This is where the graph is constant. All other intervals are either increasing or decreasing.

Saying "The graph is constant" basically means "constant rate of change", which is another way of saying that the graph isn't changing. Constant means it stays the same.

So this is why the answer is $-4 \le x \le -2$

Note how only choice A has both endpoints in the negative region, so it is a quick way to spot the answer.
