We know that 1 feet is 12 inches. Lets create a ratio to find out how many inches are in 8 feet. From there we can convert them into cm.
If 1 feet is 12 inches,
Then 8 feet is x inches.
Cross multiply in order to create the equation. 1 times x equal 8 times 12.
x=8*12
x=96 inches.
Lets create another ratio but this time to find how many cm is 96 inches.
If 1 inch is 2.54cm,
Then 96 inches is y cm.
Cross multiply in order to create the equation. 1 times y equals 96 times 2.54.
y=2.54*96
y=243.84cm
