The volume of a rectangular prism can be calculated as

Since the width is 2 cm and the height is 4 cm, then

We can use the equation:
7 x + 11 y = 500
where x is the amount of the 7 ounce weights while y is
the amount of 11 ounce weights.

this is solved through trial and error.
By trial and error I got:
x = 7 and y = 41

So that;</span>
7 * 7 + 11 * 41 = 500
49 + 451 = 500
500 = 500
<span>Hence they can use 41 11-ounce weights and 7 7-ounce
weights to test</span>
