2 answers
12, 144, 14300%
(answer explained)
1110% = dimensions x 12
12^2= 144
x 1444 original surface area
% increase = 144-1/1 x 100
=14300
Therefore the surface area is 14300% larger
1110% = dimensions x 12
12^2= 144
x 1444 original surface area
% increase = 144-1/1 x 100
=14300
Therefore the surface area is 14300% larger
