can anyone tell me these fomulas?

Question

can u tell me these formulas?????

formulas to find :-
1> area of a triangle
2> area of a rectangle
3> area of a square
4> volume of a triangle
5> volume of a rectangle
6> volume of a square
thats all guys thankyou

Answer 1

1) 1/2 * base * height
2) width * length
3) width * length (but width and length are the same)
4) 1/2 * base * height * depth
5) width * length * depth
6) width * length * depth (again.. width and length should be the same)

Answer 2

1> area of a triangle -
lets assume the triangle has sides named A, B and C; and their length a, b and c
Also, assume the angle between side A and B is O
Now the formula goes like, (1/2).a.b.Sin(O), now if O = 90 degree,
Sin(O) = 1, so it becomes, (1/2).a.b

2> area of a rectangle
Lets say the side length of the rectangle are a,b,a,b
So the area is a.b

3> area of a square
The sides are a,a,a,a
So the area is square(a)

4> volume of a triangle
5> volume of a rectangle
6> volume of a square
Triangle, Rectangle and Square - all are of two dimension. So, this is invalid to ask the volume. Only there is area.

that's all guys thank you - you welcome.

Answer 3

1/2 base times height = triangle
length times width = rectangle
square = rectangle
volume of triangle = triangle area
volume of rectangle = area rectangle
volume of square - same as area square

Answer 4

area of triangle= 1/2 ( base * height)
area of rectangle:= length * breadth
area of square= side*side
the other three questions are ridiculous
triangle,rectangle,square are 2D ,they dont have volume. they only have area.

Answer 5

1> half base into altitude,
2> length into breadth
3) side squared
4) triangle does not have volume
5) RECTANGLE DOES NOT HAVE VOLUME
6) SQUARE DOES NOT HAVE VOLUME
that is all my questionair, thanq
Volume is height x breadth x height (cubic meter or cumic feet is the unit of volume)

Answer 6

answer to 4) 5) 6) is 0 .. triangles, rectagles and squares are 2 dimensional shapes. they don't have any volume

1) 1/2 ab sin C (general formula)
2) w*l
3) w^2

Answer 7

1-----1/2 base x height = (1/2).b.h
2-----length x breadth = l.b
3-----length squared = l ²
4 ----triangle prism of height H has volume = (1/2)b.h.H
5-----rectangular prism of height, H has volume = l.b.H
6----square prism of height , H has a volume = l ². H

Answer 8

area of tirangle= (breadth*height)/2
area of rectangle=length*breadth
area of square= side^2

In your last 3 Q, VOLUME is regarded to 3-dimension.
so,please ask your Q.properly...

Answer 9

1>1/2 base x height
2>length x breadth
3>side square
4>1/2 base x height
5>l x b
6>side sq.

Answer 10

1>1/2 X base X height
2> l X b
3> (side) X (side)
