We have been given that the volume of cube is 64 cubic mm. We are asked to find the side length of the cube.
We will use volume of cube formula to solve our given problem.
, where
V = Volume of cube,
s = Side length of cube.
Upon substituting the given volume in above formula, we will get:

Now we will take cube-root on both sides of equation.
![\sqrt[3]{64}=\sqrt[3]{s^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%3D%5Csqrt%5B3%5D%7Bs%5E3%7D)
![\sqrt[3]{4^3}=\sqrt[3]{s^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4%5E3%7D%3D%5Csqrt%5B3%5D%7Bs%5E3%7D)
Using rule
, we will get:

Therefore, the side length of the cube is 4 mm.
Answer:
x = 11
Step-by-step explanation:
4x + 7 = 3 (2x - 5)
4x + 7 = 6x - 15
-2x + 7 = -15
-2x = -22
x = 11
This is known as "5 take 3", where ordering is not important.

Expressions can be read as how many times you're multiplying a number by itself.
(1/2)^4 can be rewriten as (1/2)*(1/2)*(1/2)*(1/2), which simplifies to 1/16
