HELP! a box of cercal measures 9,5 inches wide, 14 inches long, and 3 inches deep. What's the volume of the cercal box?

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square

Not a smart person, but pretty sure i need a diagram to solve (not enough information given to solve)

We know on the regular cosine graph, it decreases from 0 to pi. so, we need to set 0 as y.0 = 4 cos(2x-pi)0 = cos(2x-pi)2x-pi = pix = piwe already know the answer, but do pi on your own!
