Answer:

Step-by-step explanation:
There are two ways we can solve this equation.
<h2>
A) Using the formula provided</h2>
The formula provided states that the volume of a cube based on the area of one of it's faces will be
, a the area of one face. Since we know the area of one face, we can substitute that inside the equation.

It's important to note that when we have a number to a fraction power, it's the same as taking the denominator root of the base to the numerator power.
So -
becomes 
Therefore, the volume of this cube will be 
<h2>B) Using prior knowledge about cubes</h2>
We can additionally use prior knowledge to find the volume of this cube.
We know that the area of a square will be
, where s is the length of a side. We also know the formula to find the volume of a cube from it's side length is
.
Since we know that one face is 100, we can make an equation - 
Now that we know the value of s, we can plug it into the volume formula,
.
So the volume is
.
Hope this helped!
Answer:

Step-by-step explanation:
The question asks:
2.16 = ???
The is a decimal number that can be converted to a mixed fraction
2.16 = 2 + 0.16
2 = whole number.
So, we are left with 0.16
We can convert this to a fraction
Since it is in 2 decimal places we Multiply by 100
=( 0.16 × 100)/ 100
= 16/100
We simplify this fraction and we have
= 4/25
Therefore,
2.16 = 2 + 0.16
2.16 = 2 + 4/25
2.16 = 
Answer:
-10
Step-by-step explanation:
y= kx
or, k= y/x
or, k = 5/4
k = 1.25
y= kx = 1.25 × (-8) = -10
