Answer:
X=-10
Step-by-step explanation:
Flip it
7X=-70
Divide both sides by 7
7x/7= -70/7
mean = sum of numbers / number of numbers
mean = (-7 +23 -5 +4)/4
mean = 3.75
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>
