A cuboidal vessel is 10 m long and 8 m wide.
Question. A cuboidal vessel is 10 m long and 8 m wide. How high must it be made to hold 380 cubic metres of a liquid?

Solution:

Let the height of the cuboidal vessel be h.

Length (l) of vessel = 10 m

Width (b) of vessel = 8 m

Volume of vessel $=380 \mathrm{~m}^{3}$

$\therefore / \times b \times h=380$

$[(10)(8) h] \mathrm{m}^{2}=380 \mathrm{~m}^{3}$

$h=4.75 \mathrm{~m}$

Therefore, the height of the vessel should be 4.75 m.
