The surface areas of two similar solids are 441 cm2 and 225 cm2. If the approximate volume of the smaller solid is 250 cm3, what is the volume of the larger solid?

volume of the larger solid = 686 cm³

Step-by-step explanation:

The solids are similar . A solid is similar if all the corresponding sides are proportional . They are similar if they are the same type of solids and their corresponding sides like height, radius etc are proportional.

The ratio of the surface area of a similar solid is equal to the square of their scale factor.

(a/b)² = 441/225

square root both sides

a/b = √441/√225

a/b = 21/15

The ratio of the volume of a similar solid is equal to the cube of their scale factor.Therefore,

(21/15)³ = a/250

9261 /3375  = a/250

cross multiply

9261 × 250 = 3375a

2315250  = 3375a

divide both sides by 3375

a = 2315250/3375

a = 686  cm³

volume of the larger solid = 686 cm³

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
