lbh = 240

new length = l/2
new width = (2/3)b
new depth = 2h

new volume = (l/2)*(2b/3)*(2h) = (2/3)lbh = (2/3)*240 = 160

Answer: Option B

Let the original volume be 100%
Volume after decrease in length = 50%
" after dec in width = 33.33%
" after inc in depth = 66.66%
The new vol = 66.66% of 240 = 2/3 of 240 = 160
