Answer: 96 cm²

Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a three-dimensional figure.

So to find the surface area of a cube, it's important to understand that each face of a cube has the same area. So we can simply find the area of one face of a cube and multiply by the number of faces, which is 6.

To find the area of one face of a cube, we can use the formula for the area of a square which is A = s². Since the length of a side is 4 cm, we have (4 cm)² or 4 centimeters · 4 centimeters which is 16 cm².

Now, since there are six sides to a cube, we have 6 (16 cm²) which is equal to 96 cm². So the surface area of the ice cube is 96 cm².

Hello,

1 .65 + 0.20(65) = 65 + 13 = 78
(65 - 60) / 65 = 5/65 = 0.0769 x 100 = 7.69 rounds to 7.7 % decrease compared to the 65 pizza's sold yesterday

A NASA spacecraft measures the rate R of at which atmospheric pressure on Mars decreases with altitude. The result at a certain

AysviL [449]

Answer:

$R = 0.0000498 \frac{KJ}{ m m^3}=0.0000498 \frac{KJ}{m^4}=4.98x10^{-5}\frac{KJ}{m^4}$

Step-by-step explanation:

For this case we have the following value:

$R = 0.0498 \frac{Kpa}{Km}$

We can convert this first to $\frac{Kpa}{m}$ like this:

$R=0.0498 \frac{Kpa}{Km} *\frac{1km}{1000m}=0.0000498 \frac{Kpa}{m}$

Now we use the fact the the pressure is defined as $P =\frac{F}{A}$ , whre P is the pressure, F the force and A the area, so then $Kpa= \frac{KN}{m^2}$ and then we can replace this:

$R=0.0000498 \frac{KN}{m^3}$

Now from definition of work we know that $W= Fd$ where W is the work, F the force and d the distance, so then is equivalent $KN =\frac{KJ}{m}$

And if we replace this into the equation we got:

$R = 0.0000498 \frac{KJ}{ m m^3}=0.0000498 \frac{KJ}{m^4}=4.98x10^{-5}\frac{KJ}{m^4}$
