Can someone very simple explain this and use an example? Part 1: Create and provide the dimensions for two similar figures of your choosing. Part 2: What is the similarity ratio of these figures along with the ratio of their surface area and volume? Part 3: Show your work, either using the actual volumes or using the formula, that the volume ratio is true.
This question i dont quite understand? Please someone help?
im assuming by two similar figure they mean the same figure with different dimensions, so use a figure like a cube that is easy to solve for surface area and volume
Ok and then?
Like can you show me how to do these problems? Its the last question of the night and im stumped ._.
so say the first cube has length=width=height=2 and the second l=w=h=4 solve for the surface area and the volume of each to start
Wait so they all equal 2? Then its be 8? Wouldnt it?
And the second one would be 64?
volume=l*w*h surface area = 6*l*w for cubes
Bleh im sorry ._. its late and im like braindead.
the similarity ratio for these would be 1/2 because the first cubes dimensions are 1/2 of the second cubes
ive been there dont worry
nnow we need to solve for the volumes and surface areas with the equations i gave you and find their ratios
Alright, so we have to solve there two numbers you gaves me for volume and surface areas using there formulas?
sorry ratio of surface area to volume would be SA/V for each cubes (the ratio will be the same for both)
yep
So i do what i just said?
yep
But you only gave me 2 numbers. when i need more then that? You gave me 2 and 4.
so for the first cube length=2in height=2in and width =2in so volume is 2in*2in*2in=8in^3 surface area =6in*2in*2in=24in^2 i just decided to use inches for my units but it could be any unit of distance
sorry surface area =6*2in*2in
Whered you get the 6 from?
because the area of a square is its hieght times its width and there are six 'faces' of a cube that are all squares
so its surface area is six times the area of on of those squares
Ohhhh.
now the ratio of surface area to volume would be 24/8=3
if you solve for the surface area and volume of the cube whose length width and height all equal four you will find its ratio to also be 3
Snap your a genius :D
Alright, so to answer my 3 questions basically, 1. (2,2,2) (6,2,2) 2. The similiarity rate is 24/8=3 And 3 is just where i show how i did it?
NOOOOOOOOOOOOOOO, you went offline ._.
Can someone please finish this? Did i do what i need to submit correctly? And if not could you please help me?
sure
