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.

I still don't get it.
