Question about Casio FX-115ES Scientific Calculator

Calculating roof height from one end to other for 14.4 meters length with 3 degrees pitch

Ad

I am not exactly sure what the 14.4 m distance represents: The horizontal part or the inclined one.

A. If the 14.4m is the length of the horizontal leg, then the height is given by tan(3 deg)=h/14.4m or h=14.4m*tan(3 deg) =0.75467 m.

B. However if 14.4 m is the length of the inclined part (the hypotenuse) of the triangle, then the height is given by

sin(3 deg)= h/14.4m or h=14.4 m *sin(3 deg)= 0.75363 m

As you can see, the values are approximately equal, because for angles less than 10 deg, the sine and tangent are approximately equal.

I am no construction engineer, but it seems to me that a 3 deg pitch in not much of an inclination. Maybe you meant 30 degree pitch.

If that be the case, the calculations are performed the same way as above: Just substitute 30 deg for 3 deg.

a^2 + b^2 = c^2

a squared + b squared = c squared, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides in a right-angled triangle.

You calculate a volume. If all the lengths, radii, heights are in feet the resulting volume is in cubic feet.

Example: Right rectangular prism with L=5 ft, W= 3 ft, height =1.5 ft

Volume =(5 ft)*(3 ft)*(1.5 ft)= (5*3*1.5) (ft*ft*ft)=22.5 ft^3

Example: Right rectangular prism with L=5 ft, W= 3 ft, height =1.5 ft

Volume =(5 ft)*(3 ft)*(1.5 ft)= (5*3*1.5) (ft*ft*ft)=22.5 ft^3

Since you have the coordinates of the three vertices, the most straightforward method is to calculate the length of the sides using the distance formula

d(P_1,P_2)=SQRT(**(X_1-X_2)^2**+(**Y_1-Y_2)^2**)

where SQRT is the**square root function**, X_1, Y_1) are the coordinates of point P_1, etc.

With the three lengths available, use Heron's (sometimes called Hero's) to find the area.

**Here is Heron's formula.**

Let's call the lengths**a, b, **and** c**

Let p be the semi-perimeter p= (a+b+c)/2

Then

Area= SQRT [**p(p-a)(p-b)(p-c)** ]

Make sure that there is a matching ) parenthesis to the one in the SQRT.

**Alternatively,**

You can choose the base as the side opposite the vertex (0,0)

Calculate the equation of the line that supports the base.

Calculate the equation of the line issuing from (0,0) and perpendicular t the base.

Calculate the coordinates of the intersection point , call it H, of the base and its perpendicular line (coming from (0,0)).

Calculate the distance OH, that is the height relative to the chosen base.

Use the formula**Area= base*height/2**

Now it is up to you to choose one of the two methods and calculate the area of that triangle. The second method involves more calculations than the first, and more possibilities of errors. Good Luck

the area of your roof is equal to the base (B) times the hight (H) divided by 2.

A = ( B x H )/ 2 = 120

To get the Perimeter of your roof you need to sum the base plus the sides (S)

So P = B + 2 x S

if you have a slope degree of 30 then

B/2 = cos (30) x S

so P = B + 2 x B / 2 / cos(30)

P = B ( 1 + cos (30) )

we also know that

H = tg (30) x B/2

from this last one we can go back to the Area and get a value for B

120 = ( tg (30) x B / 2 x B) / 2

480 x SQRT(3) = B^2

B = SQRT(480/tg(30))

So:

P = SQRT(480/tg(30)) x ( 1 + cos (30))

tg (30) = 1 / SQRT(3) cos (30) = SQRT(3)/2

P = 2 SQRT(30 x (12 + 7 x SQRT(3) ) ) or aproximately 53.8m

A = ( B x H )/ 2 = 120

B = SQRT(480/tg(30))

So:

P = SQRT(480/tg(30)) x ( 1 + cos (30))

tg (30) = 1 / SQRT(3) cos (30) = SQRT(3)/2

P = 2 SQRT(30 x (12 + 7 x SQRT(3) ) ) or aproximately 53.8m

Now **cubic meter calculator **can be defined as a
simple device which is used to convert a given value in meters to it's
corresponding cubic meter form. Other than this we can always add the
formulaes of the structures to get the volume of the structure by
simply entering it's side length or height etc..

Let us consider simple examples :

Suppose that we have to convert 5 meters to its cube. The only thing we would do is that we would enter this value of 5 in the calculator and calculator with do the calculation as and will show the result to you as 125 .

Now if we have added formulaes to this calculator , like for calculating the volume of cube,cylinder and cone (say). Then we can use this calculator in three different cases.
