Question

A cuboidal fish tank 91cm long,66cm wide and 60cm deep is filled with water to
the brim.Water from the tank is emptied with the help of a cylindrical container
of diameter 14cm and height 15 cm.How many containers of water are
removed to empty the tank?

Answer 1

Answer:

156 is the correct answer

Answer 2

156 containers of water are removed to empty the tank.

Step-by-step explanation:

Consider the provided information.

A cuboidal fish tank 91cm long,66cm wide and 60cm deep is filled with water to  the brim.

Calculate the volume of the box using the formula: $V=lbh$

Substitute the respective values in the above formula.

$V=91\times66\times60$

Also, the tank is emptied with the help of a cylindrical container  of diameter 14 cm and height 15 cm.

Now calculate the volume of cylindrical container by using the formula:

$V=\pi r^2h$

Substitute r=7 and h=15 in above formula.

$V=\frac{22}{7}\times 7^2\times15$

$V=22\times 7\times15$

Now divide the volume of cuboid with volume of cylinder.

$\frac{91\times66\times60}{22\times 7\times15} =13\times12=156$

Hence, 156 containers of water are removed to empty the tank.
