are the two figures similar? If so, give the scale factor of the first figure to the second figure. two cubes, one with 3-cm edges, the other with 4.5-cm edges

Similar in area or circumfrance?

OpenStudy (australopithecus):

If you were looking for area C*((base*height Fig 1.1) + Base*Height fig 1.2)) = Base*Height Fig. 2 solve for C Do the same for circumferance only the formula is slightly different but you should be able to come up with it yourself

Any questions

C is your scale factor, a scaler is just a number that you multiply by another number to make that number equal to another number, essentially A*C = B where, C is your scale factor, or scaler

it is a cube and you lost me with C*((base*height Fig 1.1) + Base*Height fig 1.2)) = Base*Height Fig. 2 solve for C

oh sorry I'm sick so yeah my comprehension is a bit lacking right now. Well I guess you want surface area and volume then (surface area cube 1 + surface area cube 2)*C = Surface area Cube 3 where, C is your scalar do the same for surface area.

the you can form an opinion on how similar the two figures are

based on the scalar determined

lol I really should edit what I write but smeh meh you follow right?

You can easily look up the formulas for surface area of a cube and volume of a cube (which is just, V = B*H*W

ok so 1.1 volume is 91.125 cm ^3 1.2 volume is 27 cm^3 like that

OpenStudy (australopithecus):

Volume of a cube = Base*height*Width |dw:1388261145838:dw| so for the first cube, Volume = 3*3*3 The second cube, Volume = 4.5*4.5*4.5
