Answer:
192
Step-by-step explanation:
The area of the cereal box = 8 x 3 x 10 = 240
Therefore, if 100% of the box is filled with
cereal, the amount of cereal in the box
will be 240.
now, 80% is x
80/100 = x/240
cross multiplying,
100x = 80×240
100x = 19 200
dividing both sides by 100
x = 192

To be a right triangle, the hypotenuse^2 must equal side1^2 + side2^2
Only set 2 meets these conditions
8, sq root (29), sq root (35) then squaring these:
64, 29, 35
64 = 29 + 35
