Answer:
draw a square using only 16 squares representing the area, so 8 by 8 by 8 by 8
The formula for volume always involves three dimensions.
In this case, the volume of a cube is 
, where 
is the side length of the cube.
To solve for that side length, you'd need to use a cube root.
The answer to this question is 27/28
Answer:
18
Step-by-step explanation:
First, I'm assuming AB=4=4x-2 was a typo and it's supposed to be AB = 4x - 2
AB=BC
AB = 4x - 2 BC = 3x + 3
4x - 2 = 3x + 3
Solve for x Add 2 to each side
4x - 2 = 3x + 3
4x - 2 + 2 = 3x + 3 + 2
4x = 3x + 5 Subtract 3x from each side.
4x - 3x = 3x- 3x + 5
4x - 3x = 5
x = 5
Now plug back in to the original equations
AB = 4x - 2 BC = 3x + 3
AB = 4 (5) - 2 BC = 3(5) + 3
AB = 20 - 2 BC = 15 + 3
AB = 18 BC = 18
So AB is 18
-3,-7.5,2 2/3 are the opposites of those numbers
