cubert(375+648+1029)=7.21+8.65+10.096=25.956 inches tall.

since these are all cubes then all sides are equal.....therefore to find the height of each block just take the cube root of each volume.
h(375)=root%283%2C375%29=7.21in
h(648)=root%283%2C648%29=8.65in
h(1029)=root%283%2C1029%29=10.1in
total height of all 3 cubes=appx. highlight%287.21%2B8.65%2B10.1=25.96%29 inches
