The first pair of weights weighs 3 lb each so all total they weigh 2*3 = <<3*2=6>>6 lbs
The second pair of weights weigh 5 lbs each so they weigh 2*5 = <<5*2=10>>10 lbs
The third pair of weights weigh 8 lbs each so they weigh 2*8 = <<8*2=16>>16lbs
All total, the entire system of weights weigh 6+10+16 = <<6+10+16=32>>32 lbs
