Question

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

Answer 1

Similar in area or circumfrance?

Answer 2

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

Answer 3

Any questions

Answer 4

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

Answer 5

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

Answer 6

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.

Answer 7

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

Answer 8

based on the scalar determined

Answer 9

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

Answer 10

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

Answer 11

)

Answer 12

yea i kinda follow

Answer 13

well if you have any questions or get stuck tell me.

Answer 14

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


like that

Answer 15

Volume of a cube = Base*height*Width



so for the first cube,

Volume = 3*3*3

The second cube,

Volume = 4.5*4.5*4.5
