Anni [7]

Answer:

The length of a side of the cube-shaped container is 2,016 units

Step-by-step explanation:

step 1

Find the volume of a cube with a side length of 1008 units

The volume of a cube is equal to

V=b^3

where

b is the length side of the cube

we have

b=1,008\ units

substitute

V=(1,008)^3\ units^3

step 2

Find the length side of the cube-shaped container  

Let    

x-----> the length side of the cube-shaped container in units

we know that

The area of the base of the cube-shaped container multiplied by 252 units must be equal to the volume of the cube with a side length of 1008 units

so

x^{2} (252)=(1,008)^3

solve for x

x^{2} =\frac{(1,008)^3}{252}

x^2=4,064,256

x=\sqrt{4,064,256}

x=2,016\ units

therefore

The length of a side of the cube-shaped container is 2,016 units

Evaluate the expression 2x^2 - x, when x = -3. Show all steps.
V125BC [204]

Answer:

21

Step-by-step explanation:

This is a substitution question,we are to substitute a given value in place of a certain letter

So let's solve

2x^2-x

And since x is given to be -3

So let's substitute

2(-3)^2-(-3)

2(9)-(-3)

18+3

21

So the final answer is 21
