1. each cylinder requires 4 bolts. how many bolts are needed for an 8 - cylinder engine?
2. a shop packs 6 spark plugs in each box. how many spark plugs are there in 15 boxes?
3. one repair kit needs 5 washers. how many washers are required for 25 kits?
4. each gasket requires 3 screws. how many screws are needed for 12 gaskets?
5. a mechanic orders 18 bottles of oil. each bottle contains 24 ounces. how many ounces of oil is that in total?

Explanation:

Step1: Multiply bolts per cylinder by number of cylinders

$4\times8 = 32$

Step2: Multiply spark - plugs per box by number of boxes

$6\times15=90$

Step3: Multiply washers per kit by number of kits

$5\times25 = 125$

Step4: Multiply screws per gasket by number of gaskets

$3\times12=36$

Step5: Multiply ounces per bottle by number of bottles

$24\times18 = 432$

Answer:

1. 32 bolts
2. 90 spark - plugs
3. 125 washers
4. 36 screws
5. 432 ounces of oil
