A sandbox is in the shape of a rectangular prism with dimensions 50 cm × 68 cm × 16 cm. The sandbox is 85% filled with sand. A new delivery of sand, roughly the shape of a cube with a side dimension of 14 cm, is to be placed in the sandbox

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
