innumeracy is the lack of ability to understand and use numbers in calculations. what are some examples of the consequences of innumeracy?
a coworker decides to plan a lunch at work. after everyone has finished their lunch, there is enough food for everyone to have seconds and even thirds. if your coworker had been able to estimate the amount needed per person, then the food that was left over would be minimal.

your friend designs a new product that claims to help people stay organized. she has had her product tested by 10 of her relatives and close friends. these 10 people gave her product great reviews which gave her false confidence that her product would be profitable. her business failed because she did not use a large enough sample size which led to unreliable results.

Explanation:

Question 6

Step1: Recall volume formula

The volume formula for a rectangular - prism is $V = lwh$. Here, the area of the base $A=lw = 500$ square feet and the height $h = 9$ feet.

Step2: Calculate volume

$V=A\times h=500\times9 = 4500$ cubic feet.

Innumeracy leads to poor quantitative - based decisions. In the lunch - planning example, not being able to estimate food amounts is an example of innumeracy. Also, in the product - testing example, not understanding sample - size requirements is a sign of innumeracy.

Answer:

$4500$ ft³
