If one meter is equal to 39.4 inches, how many centimeters are in one foot?
Answer 30.4 cm
How is this answer obtained?
i know there is 12 in in a foot
and 100 centimeters in a meter.
what happens next?
1ft*12in/ft*100cm/39.4in= xxx cm
I know!
(1 m/39.4 in)(12 in / 1 ft)(100 cm/m)
= 30.46 cm / ft
because
(m/in)(in/ft)(cm/m) = cm/ft
Well, to convert inches to centimeters, we can use the conversion factor of 2.54 centimeters in 1 inch. Since there are 12 inches in a foot, we can multiply this by 2.54 to get the number of centimeters in a foot.
12 inches * 2.54 centimeters/inch = 30.48 centimeters
So, there are approximately 30.48 centimeters in one foot. Now you know why height is measured in feet and inches - it sounds much more impressive than centimeters!
To find the number of centimeters in one foot, we can use the conversion factors:
1 meter = 100 centimeters
1 meter = 39.4 inches
First, let's convert feet to inches. Since there are 12 inches in one foot, we can multiply the number of feet by 12 to get the equivalent inches.
1 foot * 12 inches/foot = 12 inches
Next, we can convert inches to centimeters. We know that 1 meter is equal to 39.4 inches, so we can set up a ratio to solve for the number of centimeters in 12 inches:
39.4 inches = 100 centimeters
12 inches = X centimeters
Using the ratio, we can cross-multiply and solve for X:
39.4 inches * X centimeters = 12 inches * 100 centimeters
X = (12 inches * 100 centimeters) / 39.4 inches
Calculating this equation, we find:
X = 30.45 centimeters
Therefore, there are approximately 30.45 centimeters in one foot. However, in this case, we can round it to 30.4 centimeters for simplicity.
