A girl of mass 50Kg runs up a flight of steps. There are 20 steps on the stair case and each step has a height of 20cm.
What is the total height of the stairs in metres?[2]
0.20 * 20 meters
To calculate the total height of the stairs in meters, we need to determine the vertical distance covered by each step and then multiply it by the number of steps.
Given that each step has a height of 20cm, we first need to convert this measurement to meters. Since there are 100 centimeters in 1 meter, each step's height in meters is 20cm / 100cm = 0.2 meters.
Next, we need to calculate the total height of the stairs by multiplying the height of each step (0.2 meters) by the number of steps (20 steps):
Total height = Height per step × Number of steps
= 0.2 meters/step × 20 steps
= 4 meters
Therefore, the total height of the stairs is 4 meters.
