Hence the answer is 480ml

Step-by-step explanation:

Given Elena wonders how much water it will take to fill her cup. She drops her pencil in the cup and notice it just fit diagonally. The pencil is 17cm long (hypotenes) and the cup is 15cm tall.

To find how much water it can hold

SOLUTION

$\sqrt{x {} ^{ 2} + x {}^{2} + 15 {}^{2} = 17 }$

$2x {}^{2} = 64$

$x {}^{2} = 32$

$x = 5.66$

therefore volume of the cup

$5.66 \times 5.66 \times 15cm|$

480cm³= 480ml
