If the volume of a cubical box is 1728cm find its total surface area

Lera25 [3.4K]

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:

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

Given that cos(30°) = cos(45°)cos(15°) + sin(45°)sin(15°), it follows that cos(30°) =

mario62 [17]

Answer:

$cos(30\°) = cos(45\°-15\°)$

Step-by-step explanation:

To solve this problem you must know the formula of subtraction of angles for the function cosx.

The formula is:

$cos(h-d) = cos(h)cos(d) + sin(h)sin(d)$

We can write 30° as: 45° - 15°

Then:

$cos(30\°) = cos(45\°-15\°)$

Using the formula for subtraction of angles we have:

$cos(45\°-15\°) = cos(45\°)cos(15\°) + sin(45\°)sin(15\°)$

Notice that we have achieved the expression shown in the statement

Finally:

$cos(30\°) = cos(45\°-15\°)$
