See the attached figure to better understand the problem
we know that
[volume larger figure]=8*8*3----------> 192 units³
[volume smaller figure]=4*5*2.9----------> 58 units³
[volume of the composite figure]=192+58----------> 250 units³
6 equals 6*10^0 which os 6*1=6
i really dont know what your saying so this is a guess but 26 is close to 30 and 53 is close to 50 so 30+50=80
i hope that helps<3
