Question

Volume and Surface Area Math help 100 points

Answer 1

Answer:

Sorry i only know part 3

surface area smaller solid=960 cm^2

and then

surface area larger solid equals scale factor^2*surface area smaller solid

surface area larger solid equals [1.625]^2*960--> 2535 cm^2

 surface area larger solid is,  2535 cm^2

Answer 2

Part 1) we have that
volume smaller solid=512 cm³
volume larger solid=2197 cm³

we know that
volume larger solid=[scale factor]³*volume smaller solid
scale factor=∛[volume larger solid/volume smaller solid]
scale factor=∛[2197/512]-----> scale factor=1.625


Part 2) 
the ratio of the surface areas is equal to [scale factor]²
1.625²-------> 2.64

Part 3)
surface area smaller solid=960 cm²
then
surface area larger solid=scale factor²*surface area smaller solid
surface area larger solid=[1.625]²*960-----> 2535 cm²
 surface area larger solid is  2535 cm²
