I would use the conversion factor:
[MATH]x\text{ ft}=x\text{ ft}\cdot\frac{12\text{ in}}{1\text{ ft}}\cdot\frac{2.54\text{ cm}}{1\text{in}}=\frac{762}{25}x\text{ cm}=30.48x\text{ cm}[/MATH]
what is this?
8x12+6=102 in
102*2.540=259.08 cm
Look at the beginning and the end. It clearly says x ft = 30.48x cmwhat is this?
8x12+6=102 in
102*2.540=259.08 cm
Back in the stone age, when I was in school, it was called the "dimensional unit method".what is this?
