Use the Fermi process to estimate the number of bricks needed to fill an empty bathtub. Show your work.

***

A typical brick is a rectangular prism with dimensions 4 in. x 2 in. x 8 in.

A typical bathtub is a rectangular prism with dimensions 60 in. x 30 in. x 18 in.

*** You can either use these dimensions or come up with your own. Like having the bricks dimensions as 7 in. x 5 in. x 2 in. and the bathtub being 48 in. x 24 in. x 24 in. Its up to you. :)

Fermi Estimate: An estimate of a very large number using the Fermi process; This process involves being able to estimate quanties and then round the estimates to the largest number that is a product of a counting number less than 10 and a power of 10.

Please Help Me!!! I have been working on this question since yesterday [5/10/18].

Thank You For All Your Help!!!!

Hi Kennedy,

I really do not understand your question.

I do not understand the estimation method that you have described and ..

Why would you use any estimation process for this?

Plus is easy and the numbers are not very big.

**So I know I am not answering your question Sorry **

A typical brick is a rectangular prism with dimensions 4 in. x 2 in. x 8 in.

A typical bathtub is a rectangular prism with dimensions 60 in. x 30 in. x 18 in.

60/4=15

30/2=15

18/8=2.25

The base layer is 15*15=225 bricks

There are 2.25 layers so 225*2.25=506.25 = 507 bricks.

alternatively

4*2*8=64

60*30*18=32400

32400/64 = 506.25 = 507 bricks
