A cube, by definition, has six sides. There cannot be a 40-sided cube.
Assuming all faces need to be painted, the question can be written as "how many faces on 43 cubes." There are 6 faces on each cube. Thus the answer can be got from the multiplication 43x6. Doing this gives us 258, so the number of faces that would need to be painted is 258.
Tom constructed a large cube using 3 cm cubes along each edge, resulting in a total of 27 smaller cubes (3 x 3 x 3). After painting the 6 faces of the large cube, he disassembled it back into individual 1 cm cubes. The painted surfaces would primarily be found on the outer layer of the small cubes. Consequently, only the cubes on the surface would have paint, while the inner cubes remain unpainted.
0 - you said it's only 1 cube even if it's a big one
This is kind of neat. I drew a three dimensional cube. Then divided the faces into 16 squares per face. Then started counting which of those little cubes would have a painted face. I get: 1 red face - 24 cubes 2 red faces - 24 cubes 3 red faces - 8 cubes 4, 5, & 6 red faces - 0 cubes
my approach.. go for the cubes which wont be on the top layer mean they wont be painted3x9x14 mean for every side there are 2 layers exposed on opposite sides.which means 1x7x12 = 84 cubes wont be painted.now painted cubes = 378-84 => 294i think m rite!!o yeah!!!
24 cubes would be it.
There would be 8 will 3 faces painted red, 24 with 2 faces painted red, 24 with 1 face painted red, and 8 that have no faces painted red.
Zero would be enough.

A 100-sided polyhedron is known as a "hectogon" or "centagon" in geometry, although it is more commonly referred to in mathematical contexts as a "100-gon" when discussing its two-dimensional form. In three dimensions, a 100-sided polyhedron would be a complex shape with 100 polygonal faces. These polyhedra can be quite intricate and are less commonly encountered than simpler shapes like cubes or tetrahedra.

8 x 5 - 4 = 36 cubes There is a possibility you mean 8^3 x 5^3 - 4^3 which would be 512 x 125 - 64 = 63936 but that would be "cubed" rather than "cubes."
