Description

A framed green chalkboard with a silver frame is displayed against an off-white background. On the chalkboard, there is a white chalk drawing of a cylinder, complete with dotted lines at the base and labels indicating 'r' for radius and 'h' for height. Above the cylinder, the formula 'v=πr²h' is written in chalk. To the right of the diagram, a photograph of a metal can has been affixed to the chalkboard with tape. The can is depicted in black and white, and it exhibits distinct ribbing and a pull-tab opening.
