HEEEELP!!!!! Aerospace/Aviation/Weather Question!!!!!!!?

I've tried studying, and i cant find out how to do this, help!!! its a lot of grades for school: From ISA to MSL, calculate the Temperature (in Celcious) and Pressure in mb and inches at the given altitude: 3450 FT 2478 M 3.52 KM 2.87 KM 3200 FT 4500 FT 8972 FT 2.78 KM 4377 M 10,154 FT 5000 FT 4650 M 3.8 KM 2000 FT 2350 FT 4450 FT 7200 FT 1500 FT Anyone? At least i need answers, or someone explaining how to do this.

1. What I understood is that you want to find out the standard values of ISA. If I am correct to assume this, then please refer the standard ISA values of temperature and pressure at MSL. the ISA also gives the rate of change with height. Apply this and u will get the answer. eg isa temp at msl is taken as 15 C. and temp gradient is 1.99 or take it 2 C. so at 3000 ft the temp isa is 15 - 6 = 9 C. msl pressure is 1013.2 hpa or 29.92 inces. So u can calculate. I hope this helps u.
