The Toblerone box is like a triangular prism; any ordinary box is like a rectangular prism.
Yellow (and black letters or symbols) for "ordinary hazards"; Orange for hazards created by temporary construction; or Pink for hazards caused by emergencies in the roadway ahead. Under the U.S. Manual of Uniform Traffic Control Devices.
A pyramid of biomass might not be pyramid-shaped due to variations in the efficiency of energy transfer between trophic levels, where some ecosystems have a large biomass of primary producers that can support a smaller biomass of herbivores and even fewer carnivores. Additionally, certain ecosystems, like those with detritivores or decomposers, can have significant biomass at lower trophic levels, which may disrupt the typical pyramid structure and create an inverted pyramid appearance.
A real-world object that resembles a pyramid is a slice of pizza, particularly in the triangular shape of a single slice. Another example is the Great Pyramid of Giza, an iconic structure itself. Additionally, a traffic warning sign, often shaped like an inverted pyramid, shares this geometric form.
A structure shaped like an inverted U.

By no means all are. Some are spherical, some are hemispherical, and some shaped like an inverted teardrop.
an inverted kiteIf it is a quadrilateral then an arrowhead. Otherwise simply call it arrow-shaped.
No; it is square-shaped, like any ordinary building.
There are no ordinary household objects shaped like a decagon. Some glasses or vases may be decagonal in shape.
The inverted U hypothesis was proposed by psychologists Robert Yerkes and John Dodson in 1908. They suggested that performance increases with arousal up to a certain point, beyond which performance declines. This relationship between arousal and performance is often depicted as an inverted U-shaped curve.
Unsure, but there are certainly many bone-shaped objects that do not seem to be just ordinary rocks.

Its usually called a conventional weeder.
The inverted U theory, also known as the Yerkes-Dodson law, suggests that there is an optimal level of arousal for performance. Performance improves with arousal to a point, but beyond that point, performance declines. It is often represented as an upside-down U-shaped curve.
