Is it B?
V = L w H
new V = (2/3)L * (1/10) w * (1/4) H
= (2/120) LwH = (1/60) LwH
new V = (2/3)L * (1/10) w * (1/4) H
= (2/120) LwH = (1/60) LwH
Yes
original dimensions: l, w, h
volume = lwh
new length --- 2l/3
new width ---- w/10
new height = h/4
new volume + (2l/3)(h/4)(w/10)
= 2 lwh/120
= lwh/60 or (1/60)lwh
so , yes, it is B
volume = lwh
new length --- 2l/3
new width ---- w/10
new height = h/4
new volume + (2l/3)(h/4)(w/10)
= 2 lwh/120
= lwh/60 or (1/60)lwh
so , yes, it is B
