this is just a shape with a peace of it cut out so if we imagine how would this figure be before it was cut. it would give us an 4×12×6 cuboid (we can use that) so first, lets caculate the volume of the bigger cuboid
[tex]6 \times 12 \times 4 = 288[/tex]
then we need to caculate the valume of the two smaller cuboids.
[tex]4 \times 4 \times 4 = 64[/tex]
[tex]2 \times 4 \times 12 = 96[/tex]
by subtracting the valume of the bigger cuboid from our two smaller ones we will have the valume of the three-dimensional figure.
65+96=160
288-160=128
