Answer:

Step-by-step explanation:

The formula of a volume of a cube:

$V=s^3$

We have

$V=1728\ cm^3$

Substitute:

$s^3=1728\to s=\sqrt[3]{1728}\\\\s=12\ cm[/texbecause[tex]12^3=1728$

The formula of a surface area of a cube:

$SA=6s^2$

(6 square faces of a cube)

Substitute:

$SA=6(12^2)=6(144)=864\ cm^2$

Answer:

864 cm^2.

Step-by-step explanation:

Each side of the box = the cube root of 1728

= 12.

AS there are 6 square sides on a cube the total surface area

= 6 * 12^2

= 6*144

= 864 cm^2.

A radio station had 205 tickets to a concert. They gave away 4 times as many tickets to listeners as to employees. How many tick

Citrus2011 [14]

Answer:

As per the statement: A radio station had 205 tickets to a concert. They gave away 4 times as many tickets to listeners as to employees.

⇒Let number of tickets Employees have x and Number of ticket Listeners have 4x

It is also, given that a radio station had 205 ticket to a concert.

⇒ $\text{Number of ticket Employees have} +\text{Number of ticket Listeners have} = 205$

Then, substitute the given values we have;

$4x + x = 205$

Combine like terms, we have;

$5x = 205$

Divide both sides by 5 we have;

x = 41

Therefore, number of tickets did they give away to employees have 41 tickets

Answer:

T = ±22

Step-by-step explanation:

Let's solve your equation step-by-step.

0=−16t2+7744

Step 1: Add 16t^2 to both sides.

0+16t2=−16t2+7744+16t2

16t2=7744

Step 2: Divide both sides by 16.

16t2

7744

t2=484

Step 3: Take square root.

t=±√484

t=22 or t=−22
