please show steps with conversions

tylerd · Answer

1 meter is about 3.28ft

tylerd · Answer

$$1km^3 \times \frac{ 1000m }{ km } \times \frac{ 1000m }{ km } \times \frac{ 1000m }{ km } =1000000000m^3 $$

danjs · Answer

same as usual conversions,  to get higher dimensions, you can still use the linear relationships

1 m = 3.28 ft


cube everything

[1 m]^3 = [3.28 ft ] ^3

1 m^3 = 3.28^3 ft^3

tylerd · Answer

$$1000000000m^3 \times \frac{ 3.28ft }{ 1m } \times \frac{ 3.28ft }{ 1m } \times \frac{ 3.28ft }{ 1m } =35287552000 ft^3$$

i used tylers US to metric ratio 3.28ft to a meter

tylerd · Answer

the key with all conversions is dimensional analysis

danjs · Answer

yes, just start with what you are given,  and multiply by ratios of 1 to change units, so they cancel correctly , till you get to what you need
