mixas84 [53]

You will find all of the surface area of all of the sides and add them together to find the surface area of the retangular prisim. So, what I would do is the front and back are both 54, so 108. The sides are 27, so 54. The top and bottom are 18, so 36. Add them together, and you will get 198. I hope this helps.

A cube has a volume of 216 cubic inches. What is the length of each edge of the cube?
KatRina [158]

Volume of a cube = (edge)^3

In this problem,

Volume = 216in^2

Edge = ?

Let's plug our values into the formula above.

216in^3 = (edge)^3

Take the cbrt of both sides.

6in = edge

The length of each edge = 6in

Solve for n 50 points <br><br> a=p(1+r/n)^rn
Andreyy89

Answer:

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

Step-by-step explanation:

a=p(1+\frac{r}{n} )^{nt}

\frac{a}{p} =(1+\frac{r}{n} )^{nt}

\sqrt[nt]{\frac{a}{p}}  =(1+\frac{r}{n} )

\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )

n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]
