Question

a rectangular water tank is 3 m long, 2 m wide and 4 m high. it contain 2.7 cubic meter of water. how many more cubic meter of water must be poured into the tank to make it half full???

Answer 1

Step-by-step explanation:

First find the volume of tank.

Volume of tank = l*b*h

=3*2*4

=24 cubic metre

Half the volume of water =24/2=12 cubic metre

More water to be needed to pour the tank half full = 12-2.7

=9.3 cubic metre

$\boxed{\red{\bold{Volume\:of\:Cuboidal \:Tank:}}}$

➠ $Length × Breadth × Height$

➠ $3 m × 2 m × 4 m$

➠ $24 m^3$

$\boxed{\bold{\red{Half\:Volume:}}}$

➠ $\displaystyle{\frac{24}{2}} m^3$

➠ $12 m^3$

$\boxed{\bold{\red{Volume\:of\:water = 2.7 m^3}}}$

$\boxed{\red{\bold{Volume \:of\: more\:water\: required:}}}$

➠ $Half \:volume\: - Volume \:of \:water$

➠ $12 m^3 - 2.7 m^3$

➠ $9.3 m^3$

$\boxed{\blue{\bold{Hence\:the\:answer\:is\: 9.3 m^3}}}$
