Answer:

$960^{3}$

Step-by-step explanation:

To find the area when the length, height an width is given, you simply multiply all these values together:

8 x 10 x 12 = 960

So the total area is $960^{3}$

Answer:

$A = 592\,ft^{2}$

Step-by-step explanation:

The surface area of a rectangular prism is given by this formula:

$A = 2\cdot w\cdot h + 2\cdot w \cdot t + 2\cdot h \cdot t$

Where:

$w$ - Width, in feet.

$h$ - Height, in feet

$t$ - Thickness, in feet.

Finally, the surface area is computed by replacing every variable:

$A = 2\cdot (10\,ft)\cdot (8\,ft) + 2\cdot (10\,ft)\cdot (12\,ft) + 2\cdot (8\,ft)\cdot (12\,ft)$

$A = 592\,ft^{2}$

Answer:

There would be 173,535 lionfish after 6 years.

Step-by-step explanation:

Since lionfish are considered an invasive species, with an annual growth rate of 67%, ya scientist estimates there are 8,000 lionfish in a certain bay after the first year, A) to write the explicit equation for f (n) that represents the number of lionfish in the bay after n years; B) determine how many lionfish will be in the bay after 6 years; and C) if scientists remove 1,200 fish per year from the bay after the first year, determine what is the recursive equation for f (n); the following calculations must be performed:

A)

8000 x 1.67 ^ n = f

B)

8000 x 1.67 ^ 6 = X

8000 x 21.691961596369 = X

173,535.692770952 = X

C)

(8000 - 1200 x 1 ^ n) x 1.67 ^ n = f

Therefore, there would be 173,535 lionfish after 6 years.
