Rectangular Tank. A rectangular tank is a generalized form of a cube, where the sides can have varied lengths. It is bounded by six faces, three of which meet at its vertices, and all of which are perpendicular to their respective adjacent faces.
Length (L) = 5 m, Width(W) = 5 m, Height(H) = 5 m
Volume (V) = Length(L) * Width(W) * Height(H)
Volume (V) = 5 * 5 * 5
Volume (V) = 125 m3
