1431 since for the top one you multiply 18 by 2 by 3 and then multiply 7 by 21 by 9. Then you add up the top block (18 times 2 times 3) by the bottom one (7 by 21 by 9) to get 1431 (108+1323)

Just split them up

V=LWH

the small one has L=18, W=3, H=2
V=(18)(3)(2)=108 cm³

the large one has L=21, W=7 and H=9
V=(21)(7)(9)=1323 cm³

total is 1323cm³+108cm³=1431 cm³

the volume is 1431cm³
