To convert feet and inches to inches, you can use the fact that 1 foot is equal to 12 inches.
Lorenz jumped 16 feet and 8 inches on his first try.
\[16 \, \text{feet} + 8 \, \text{inches} = (16 \times 12) + 8 \, \text{inches} = 192 + 8 \, \text{inches} = 200 \, \text{inches}\]
So, Lorenz jumped 200 inches on his first try.
