Answer:

We need (i) the volume of the tank.............

Explanation:

#"Tank volume"# #=# #100*cmxx50*cmxx30*cm#

#=# #150000*cm^3#

But #rho_"water"=1*g*cm^-3#

And (ii) the relationship between mass, density, and volume.

Thus #"mass"="volume"xx"density"#

#=150000*cm^3xx1*g*cm^-3xx10^-3*kg*g^-1#

So that gives me over #100*kg#.
