⭐Volume of Cubical Tank => 91125 m³

⭐Volume of a cube => a³


=>> a³ = 91125

=>>a = 45 m


▪Hence the height is 45 m


✔By collecting rain water , Maria is showing concern towards water conservation .

Answer 2

The answers are as follows:

i) The height of the tank is 45 meters.

ii) By collecting rainwater in a tank and using it for watering the plants in her garden, Maria is promoting rainwater harvesting.

Given: Volume of a cubical tank = 91125 m³

To Find: Height of the tank.

Solution:

Let the dimensions of the cube be 'a' meter.

Since the cube is in the shape of a square, its length, breadth, and height all will be a meter.

∴ The volume of a cube = a³

Substituting the values we get,

91125 = a³

⇒ a = $\sqrt[3]{91125}$ meter

      = 45 meter

Answer: The height of the tank is 45 meters.
