With great difficulty since such a shape cannot exist. A cuboid, by definition, has six faces (sides).

length *width*height=area of cuboid

Make it infinitesimally small.

Surface area of a cuboid with sides x, y and z is 2(xy+yz+zx) So surface = 2*(1.45*1.45 + 1.45*5 + 5*1.45) = 2*16.6025 = 33.205

length *width*height=area of cuboid

A cuboid is a hexahedron. That is a solid face with six faces. More specifically, all six faces of a cuboid are rectangular. The total surface area of a cuboid with sides of length A, B and C is 2*(AB + BC + CA) sq units.

Let its dimensions be a, b and c:- Surface area of the cuboid: 2*(a*b)+2*(b*c)+2*(a*c) in square units

yes

Make it infinitesimally small.

The answer depends on what information is provided: the volume, total surface area, principal diagonal, minor diagonal, etc.
