A box of cereal measures 8 in by 3 in by 10 in. 80% of it is filled with cereal. How much cereal is in the box?
Anon25 [30]

Answer:

192

Step-by-step explanation:

The area of the cereal box = 8 x 3 x 10 = 240

Therefore, if 100% of the box is filled with

cereal, the amount of cereal in the box

will be 240.

now, 80% is x

80/100 = x/240

cross multiplying,

100x = 80×240

100x = 19 200

dividing both sides by 100

x = 192
