\n" ); document.write( "V(A) = (1/3)(base)(height) = (1/3)(144)(8)=384

\n" ); document.write( "V(B) = 3456

\n" ); document.write( "V(B)/V(A) = 3456/384 = 9

\n" ); document.write( "The volume of pyramid B is 9 times the volume of pyramid A.

\n" ); document.write( "However, the answer to the question as asked in the post is 8, not 9, because the question was how many times BIGGER the volume of pyramid B is than the volume of pyramid A.

\n" ); document.write( "\"9 times as big as\" is NOT the same as \"9 times bigger than\".

\n" ); document.write( "\"9 times BIGGER THAN x\" is x, plus 9 times x, which is 10x.

\n" ); document.write( "So, with pyramid B having a volume 9 times AS BIG AS pyramid A, the volume of pyramid B is 8 times BIGGER THAN the volume of pyramid A.

\n" ); document.write( "ANSWER: 8
