Answer:
-7
Step-by-step explanation:
Because zero is the x, so x=-7 then it's -7
Zero would mean the sea level. Since three miles below sea level is -3, and 0-3 is -3.
First, calculate for the volume of the cube before each edges are cut.
V = e³
where e is the length of each sides. Substituting the known value,
V = (4/5 cm)³ = 0.512 cm³
Then, calculate for the volume of each of the small cubes cut out from the corners.
V = (1/5 cm)³ = 0.008 cm³
Since there are 8 of these small cube, we multiply the volume by 8.
8V = 8(0.008 cm³) = 0.064 cm³
Then, subtracting the volumes will give us an answer of <em>0.448 cm³</em>
I can't really give you much of an answer, unless you are asking me what 1 - 8 is, in which case I will tell you that the answer is -7.
