The original statement is true.

Work Step by Step

$1~kg= 1000~g$ $1~lb \approx 0.45~kg$ $1~oz \approx 28~g$ We can convert 32,600 grams to units of kilograms. We need to move the decimal point 3 places to the left. 32,600 g = 32.6 kg We can convert 4 pounds to units of kilograms. $4~lb = \frac{4~lb}{1}\times \frac{0.45~kg}{1~lb} = 1.8~kg$ We can convert 36 ounces to units of kilograms. $36~oz = \frac{36~oz}{1}\times \frac{28~g}{1~oz}\times \frac{1~kg}{1000~g} = 1.008~kg$ The original statement is true.
