The cubic feet boxes that can be stored is given as 312 cubic feet
How to solve for the cubic feet
There are two cuboids in this shape here
Volume = V₁ + V₂
This is the total volume
The cube volume has the formula to be given as
V = abh
Such that the volume of cuboid 1
= 2 x 2 x 6
= 24
The volume of cuboid 2 is given as 6 * 8 * 6
= 288 cubic feet
The total volume is given as
24 + 288
= 312 cubic feet
The cubic feet boxes that can be stored is given as 312 cubic feet
