36 / 12 is 3
The length of a wire is 36cm, which is the sum of the edge lengths, that is, the sum of the edge lengths is divided by the number of the edge lengths, and the edge length is 3cm
If we make a cuboid frame 3cm high and 2cm wide, the formula is: 36-3 * 4 + 2 * 4 equals 16
Find the total length of cuboid edges: (length + width + height) * 4. The height is unknown. There are 4 edges for length and width respectively. Subtracting length * 4 + width * 4 from the total length of cuboid edges is equal to height

Use a 96cm iron wire to weld a cube frame. How long is each edge of the frame?

96 / 12 = 8 (CM), a: the edge length of this frame is 8 cm

Use a 360cm long iron wire to make a cube frame. How many decimeters is the length of each edge of the cube frame?

3 decimeters
