Expert Answer:

begin mathsize 16px style straight i right parenthesis space Volume space of space water space taken space out space of space tank
equals length space of space the space tank space cross times width space of space the space tank cross times fall space in space level space of space water
rightwards double arrow 540 space straight m cubed equals 25 space straight m cross times width space of space the space tank space cross times 1.8 space straight m space
rightwards double arrow width space of space the space tank equals fraction numerator 540 over denominator 25 cross times 1.8 end fraction space straight m space equals 12 space straight m space

ii right parenthesis space Total space capacity space of space water space which space tank space can space hold
equals length space of space the space tank cross times width space of space the space tank cross times depth space of space the space tank
equals 25 space straight m cross times 12 space straight m cross times 7.5 space straight m
equals 2250 space straight m cubed end style
