We are given a rectangular tank with length 250 cm and width 120 cm. We pour 180 liters of water into the tank. We need to calculate the height of the water in the tank in cm.

1. Problem Description

We are given a rectangular tank with length 250 cm and width 120 cm. We pour 180 liters of water into the tank. We need to calculate the height of the water in the tank in cm.

2. Solution Steps

First, we need to convert the volume of water from liters to cubic centimeters. We know that 1 liter = 1000 cubic centimeters.

$180 \text{ liters} = 180 \times 1000 \text{ cm}^3 = 180000 \text{ cm}^3$

Next, we know that the volume of a rectangular prism (which the water will form) is given by:

$V = l \times w \times h$

where $V$ is the volume, $l$ is the length, $w$ is the width, and $h$ is the height.

We are given the length $l = 250$ cm, the width $w = 120$ cm, and the volume $V = 180000$ cm$^3$. We need to find the height $h$.

$180000 = 250 \times 120 \times h$

$180000 = 30000 \times h$

$h = \frac{180000}{30000}$

$h = 6$

Therefore, the height of the water in the tank is 6 cm.

3. Final Answer

A. 6.0cm
