what power can you write to represent the volume of the cube shown? write the power as an expression with a base and an exponent
sergiy2304 [10]

Answer:

The power for the volume of the cube is '3'.

Exponent form of the volume is (\frac{1}{3})^3

Volume of the cube is \frac{1}{27} inch³.

Step-by-step explanation:

We are given,

A cube with side equal to \frac{1}{3} inches.

As we know,

Volume of a cube = side^{3}

Thus, we get,

Volume of the given cube is,

Volume = (\frac{1}{3})^3

i.e. Volume = \frac{1}{27} inch³

Thus, we have,

The power for the volume of the cube is '3'.

Exponent form of the volume is (\frac{1}{3})^3

Volume of the cube is \frac{1}{27} inch³.

julsineya [31]
Good afternoon, 

First side= 8cm 
Third side= x
Second side= 2x-4

We know that the sume of the lenghts of any two sides must be greater than the third side, so:

Second \,\,\,\,side+Third\,\,\,\,side>First\,\,\,\,side \\ 2x-4 + x >8 \\ 3x>12 \\ x>4&#10;

<span>Answer: Third side= x                        ;         where: x>4 or (4,+infinity)
                Second side= 2x-4              ;        </span><span> where: x>4 or (4,+infinity)</span>
