How do you find the surface area of a 3 meter cube?
Each face has a surface area of 3 x 3.As there are 6 faces, the total surface area is 6 x 3 x 3 = 54 square metres
What does cube stand for in math?
A cube is a 3 dimensional shape that has 6 faces, 8 vertices and 12 equal edges and its volume is measured in cubic units. Also its other meaning is as for example the cube of 3 is 9 and the cube root of 9 is 3
How do you find the surface area of 3 stacked cubes?
If they are all the same size, the surface area is just the total surface area, which is 6 (faces) x edge x edge - that is the area of one face, (the length of one edge times itself as cubes have square faces) x the number of faces (6) x the number of cubes (3). Then subtract fom this the area not exposed, which is the top face of the bottom cube, top and bottom of the middle cube and bottom face of the top cube - so that's 4 faces. So the formula boils down to: 6 x 3 x edge x edge - 4 x edge x edge ... or ... 14 edge² If they are different sizes: 1. Work out the total area of each cube. 2. Between the bottom and middle cube, take the smaller and that face is hidden on both cubes, so subtract twice this face. 3. Do the same for the top and middle cubes.
How many right angle on a face of a cube?
On any given face, there are 4 right angles. On an entire cube there are 6 faces, so 6 X 4 = 24 right angles on a total cube
How many arms a cube has?
A cube has 12 edges, and each edge is shared by two faces. Since each face has four edges, a cube has a total of 4 edges per face x 6 faces = 24 edges. Each edge is shared by two faces, so we divide 24 edges by 2 to get the total number of unique edges on a cube, which is 12.
