Answer:

Part 1) V=8,748\ in^3

Part 2) SA=2,754\ in^2

Step-by-step explanation:

<u><em>The correct question is</em></u>

Find the volume and the surface area of a rectangular prism. Bases are squares with sides that measure 27 inches. The height is 12 inches.

Part 1) Find the volume of the prism

The volume of the prism is equal to

V=Bh

where

B is the area of the base

h is the height of the prism

<em>Find the area of the base B</em>

B=27^2=729\ in^2 ---> the base is a square

we have

h=12\ in

substitute

V=(729)(12)=8,748\ in^3

Part 2) Find the surface area of the prism

The surface area of the prism is equal to

SA=2B+Ph

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

<em>Find the perimeter of the base P</em>

<em></em>P=4(27)=108\ in<em></em>

substitute the values in the formula

SA=2(729)+108(12)=2,754\ in^2

Don put $4,000 in a savings account with an interest rate of 4% for three years. If the interest is compounded annually, how muc
miskamm [114]

Answer:

$4,499.46

Step-by-step explanation:

We can use the compound interest formula for this problem:

A=P(1+\frac{r}{n} )^{nt}

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, lets change 4% into a decimal:

4% -> \frac{4}{100} -> 0.04

Now lets plug the values into the equation as shown below:

A=4,000(1+\frac{0.04}{1})^{1(3)}

A=4,499.46

Don will have $4,499.46 at the end of the three years.
