Answer 2

Break down the figure into 2 separate rectangular solid and find each volume and sum it.

Volume of smaller step: The volume of any rectangular solid is given by,

$V=length*width*height$

So we have $V=8*4*3=96$

Volume of larger step: The only dimension that is different than the smaller step is of the height, which is 6. So we have,

$V=8*4*6=192$

Hence, the volume of the whole figure, in cubic inches, is

$V= 192+96=288$. Answer choice B.
