=√2×3×3×3+√2×5×5×3
=3√6+5√6
=8√6
=8×2. 44
=19. 59
Step-by-step explanation:
EQUATION: Volume=length x width x height.
V=l×w×h
1620cm^3=9cm×9cm×xcm
1620cm^3=81cm^2 ×xcm
xcm= 1620cm^3/81cm^2
xcm= 20cm
Assuming ur solving for n
2/7n=8/5
Sinc edits a proportion cross multiply
now you’d get 28=5n
Or if you solve
n= 28/5 or 5 3/5
