Answer:

\Huge \boxed{\mathrm{2 \ cm }}

Step-by-step explanation:

\sf Volume \ of \ cuboid= length \cdot width \cdot height

The width is 8.5 cm.

The height is 13 cm.

The volume is 221 cm³.

221 = l \cdot 8.5 \cdot 13

Solving for l

221=l \cdot 110.5

Dividing both sides by 110.5

2=l

The length is 2 cm.

A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 6 cm per minute
alexira [117]

Answer:

Step-by-step explanation:

I think the question below is the one you wanted to ask:

<em>A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 6 centimeters per minute. After 20 minutes, the water level is 220 centimeters </em>

<em>Graph the pool's water level (in centimeters) as a function of time (in minutes).</em>

Here is my answer:

To draw the linear line, we need to identify the equation that modles this situation. As we know the water level rises at a rate of 6 cm per minute which mean the slope m = 6

The standard form is: y = mx + b <=> y = 6x + b

After 20min the water level is 220 cm

<=> 220 = 6(20) +b

<=> b = 100  

So your  equation is : y = 6x + 100 and the initial amount of water in it is 100
