It should be solid cuboid

Then in that case

Let the dimensions of the solid cuboid be 4x 3x 2x cm respectively.

Given surface area of cuboid = 832 sq cm

Surface area of cuboid= 2(lb+bh+hl)=832

Which give x=4 by putting values of l,b, and h .

Then,

Dimensions of the block are 16cm, 12cm and 8cm

Volume of cuboid  =Lbh
