The area of one face of the cube is 64 cm2. Find: edge of a cube volume of a cube the sum

The area of one face of the cube is 64 cm2. Find: edge of a cube volume of a cube the sum of the areas of all faces the sum of all edges.

The area of one face of the cube is 64 cm2. find: edge of a cube volume of a cube sum of areas of all faces sum of all edges

1) The area of one face of a cube is the product of its two faces. It is equal to 64sq.cm, since all the faces of the cube are equal, the face will be equal to 8cm.

2) The volume of a cube is the product of its three edges:

8 * 8 * 8 = 512cc.

3) The cube has 6 faces, then the sum of the areas: 64 * 6 = 384 cm².

4) The sum of the edges: The cube has 12 faces, so the sum of the faces is 8 * 12 = 96 cm

Answer:

Cube edge: 8 cm.

Volume: 512 cm³.

Total area: 384 cm².

The sum of the edges: = 96 cm.
