A stack of 500 pieces of paper is 1.875 inches tall. Diego guesses that each piece of paper is 0.015 inches thick. Explain how you know that Diego’s answer is not correct.
Compute the thickness of each piece of paper. Show your reasoning. (upload your work when complete - no work, no credit.)

If there were 1000 sheets of paper, then the thickness of each sheet would be 1.875 in divided by 1000.

1.875/1000 = 0.001875

Since there are 500 sheets of paper, each one is twice as thick as 0.001875, so each sheet is 0.00375 inches thick. 0.015 is much greater than 0.00375, so it must be incorrect.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
