If it takes 471 cm² of plastic to make a 15 ounce bottle how much plastic should it take to surround a similarly shaped 2.5 ounce bottle

78.5 cm² of plastic is needed to make a similar shaped 2.5 ounce bottle.

Step-by-step explanation:

It is given that,

It takes 471 cm² of plastic to make a 15 ounce bottle.

Let us assume,

The plastic required to make 2.5 ounce bottle = x cm²

To find the x value:

Comparing the given data,

471 plastic / 15 ounce bottle = x plastic / 2.5 ounce bottle

Keeping x alone on one side and cross multiplying the denominator,

(471 / 15) * 2.5 = x

31.4 * 2.5 = x

78.5 = x

Therefore, the value of x = 78.5 cm²

The plastic required to make 2.5 ounce bottle is 78.5 cm²
