If a large Rubik's cube has a volume of 1,331 cubic inches what is its surface area?

1 answer:

5 0

V=(4/3)pir^3
SA=4pir^2

so

given
v=1331
1331=(4/3)pir^3
times both sides by 3/4
998.25=pir^3
divide both sides by pi
998.25/pi=r^3
cube root both sides
∛(998.25/pi)=r

ok
SA=4pir^2
SA=4pi(∛(998.25/pi))²
SA=4pi(∛(996503.0625/(pi²)))
SA=4pi∛(996503.0625/(pi²))
use your calculator
SA=585.15307930795 in²

its surface area is about 585 in²

Step-by-step explanation:

I assume this is a 2 by 2 matrix.

$\begin{bmatrix} -5 & 1\\1 & 4 \end{bmatrix}$

determinant = -5 * 4 - 1 * 1 = -20 - 1 = -21

kelly has 4times as many songs on her music playlist as lou . tiffany has 6 times s many songs on her playlist as lou . altogeth

Dmitriy789 [7]

Hello! To answer this question we have to make an equation. In this equation I will represent the total number of songs Lou has as the variable x.

So 4x +6x + x = 682

This simplifies to 11x = 682. When you divide both sides by 11 you get x = 62. This is how many songs Lou has.

Since we are trying to find how many songs Kelly has, we must multiple 62 x 4 to get 248. Kelly has 248 songs.

Aleks04 [339]

Answer:

21 cm

Step-by-step explanation:

The perimeter is the length of the outside of a shape. In this case, we can simply add up all the edges and multiply by .5(the length of one edge).

Horizontal Edges: 22

Vertical Edges: 20

Total: 42

Perimeter = $42 * 0.5 = 21 cm$
