What is the volume of this figure?

A three dimensional figure with sides labeled with values. What is the volume of this figure?

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 cuboid6*12*4=288

THen we need to calculate the volume of the two smaller coupids

4*4*4=64

2*4*12=96

by subtracting the volume of the bigger coupid for our two smaller ones we will have the volume of the tree dimensional figure

65+96=160

288-160=128
