Heat and Thermodynamics question

2021 · 24 Feb · Shift 1 · Q50

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
Each side of a box made of metal sheet in cubic shape is 'a' at room temperature 'T', the coefficient of linear expansion of the metal sheet is 'α\alphaα'. The metal sheet is heated uniformly, by a small temperature Δ\DeltaΔ T, so that its new temperature is T + Δ\DeltaΔ T. Calculate the increase in the volume of the metal box.
