so first you say base x height so your base and height for bethany is
2ft,4ft,6ft then you will multiply all your heights with your bases 2ft x 6ft=12ft squared 2
4ft x 6ft=24ft squared 2
6ft x 6ft=36ft squared 2
why you square is because you no what im going to show you all i know about this subject and hope it can help your formula
where...
base 1=length of base 1
base 2=length of base 2
height=perpendicular distance
between base 1 and base 2
formula example 1
A=(b1+b2)h
A=(2+4)2fraction of 2 underneath
A=6 x 2 fraction of 6 underneath
which equals A=6cm squared 2 in a rectangular prism there is always 2 opposite sides that have the same area,
to find the surface area, the sides, multiply by LxW and multiply by 2.
since there are 3 sets of sides we have to make 3 calculations and add the together.
LxW is one set
LxH is another set
WxH is the third set
example: set 1=(2)x(8)x(5)set 1 surface area is 80cm squared
set 2=(2)x(8)x(3)
set 2 surface area is 48cm squared
set 3=(2)x(5)x(3)
set 3 surface area is 30cm squared
to find the total surface area, add the numbers together.
the total surface area of the cube is 158cm squared
and your volume of a rectangular prism is (whi) which means
w=width
h=height
l=length
the entire volume of a garden bed is 72ft squared 2 that is in the cse of the garden bed we are solving i got that answer by multiplying (whi) then add my calculation of my answers with my multiplication answers and said ok well
12+24+36= 72ft squared 2
so know we can move on to tori
i was going to help you with tori but it only shows stuff about bethany and the garden bed i guess to question 6. that you asked i would say now 1 because u didnt show what it was for the calculations and 2 u cant solve somthing thats not there :) i hope i could help :)
