If the edge of the cube is doubled what will be the surface area

edge of the cube is doubled. say it is represented by a.

so edge of the cube becomes 2a.

new surface area (S. A1) of the cube is

=6(2a)2=6(4a2)=24a2 sq.

hope this helps- ♥

surface area=6a^2

ATQ,

surface area= 6(2a)^2

=64a^2

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
