1. Calculate the volume of entire cube as if it was a solid rectangle:
Length x width x height=
20x16x12 = 3,940 cubic inches

2. Calculate the volume of the "missing"
Piece and subtract:
Length x width x height=
20x8x6 = 960 cubic inches
(notice you can find the height of the missing piece by subtracting 12-6)

So your answer is 3,940-960 = 2,980 cubic inches inside the steps

You would do 14*4 which equals 56 so if you did that to every side you would get the number of the bigger shape so you would to find x is 3*4 which equals 12 so the answer is x=12

For which of the following compound inequalities is there no solution?

meriva

Answer:

Step-by-step explanation:

$3m - 12 > 30 \text{ and } -6m\geq 24$

$\boxed{3m - 12 > 30 \wedge -6m\geq 24}$

$m>14 \wedge m\leq -4$

There's no solution. It is the first one already. There is no number that is both greater than 14 and less than or equal to -4. That is no solution because there's no $m$ that satisfy the compound inequality.
