Jaron Walker · Answer 1

900 cm^3 * 8.15 g / cm^3 = 7335 g for each part

7335 g * 1 kg/1000 g = 7.335 kg

each part weighs 7.335 kgs

they are buying 300 parts

300 * 7.335 kg = 2200.5 kg for the 300 parts

It cost $.37 per kg

2200.5 kg * $.37 per kg = $814.185 for the 300 parts

To the nearest dollar

$814
