Answer:
The measured side is not shown, so i will answer in a general way.
A cube is a 3-dimensional object with 6 square faces.
You know that all the sides of a square have the same length, then is the same for the cube.
To calculate the volume of a cube, we start with the area of the base.
The base is a square of sidelength L (Suppose that L is the length of the measured side)
The area of the base is:
A = L^2.
To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).
And the height of the cube is also L.
Then the volume is:
V = L*a = L^3
B is the answer to the question 6.8
Answer:Decreasing
Step-by-step explanation:
Focus only on the 8-10 interval for x. Note that for x=8 , y=1, for x=9, y=0 and for x=10, y=-1. Y is obviously decreasing for 
.
ANSWER:
50.88
STEP BY STEP
First you would do 64 x .25 which is 16
Then you would take the 16 away from 64 so it would be 48
Then you have to add the tax so it would 48 x .06 = 2.88
Finally you would add the 2.88 to 48 which is 50 .88
