Let the height of the tree be x and use trigonometry and the tangent ratio: x/800 = 135/45 x = 2400 cm = 24 m
The height of a human is usually measured in cm.
4'9 = 57 in 57in x 2.54 cm/inch = 145 cm 145 cm/ 100 cm/m = 1.45 m
100 cm = 1 m ⇒ 300 cm = 300 ÷ 100 m = 3 m
There are 100 cm in 1m. 1cm = 1/100m = 0.01m 4cm = 4/100m = 0.04m If you start dealing with area then things change abit as 1m^2 = 1m*1m = 100cm * 100cm = 10000 cm to go from: cm -> m divide by 100 m -> cm multiply by 100 cm^2 -> m^2 divide by 10000 m^2 -> cm^2 multiply by 10000 cm^3 -> m^3 divide by 1000000 m^3 -> cm^3 multiply by 1000000
