Solution:

(e) Volume of Equipment =

= {1}/{3} \× 3.14 ×(0.5)^{2} \× 7=1.83166

\∵\ 1.83166 \ {cm}^{3}

can write 330 words

\∴\ 1 \ {cm}^{3}

can write

=\ {330}/{1.83166}

words
Now, 1 litre

=1000 {cm}^{3}=1000 {ml}

∴ \ {3}/{5}

litre

= {3}/{5} ×1000=600 {cm}^{3}

∴ \ 600 \ {cm}^{3}

can write

= {330}/{1.83166} × 600

words

= 10800

words
