Six pyramids are shown inside of a cube. The height of the cube is h units. The lengths of the sides of the cube are b.The area

Viefleur [7K]

Step-by-step explanation:

Cubes have square faces, so the area of the base is b².

The volume of the cube is b³.

The height of each pyramid is half the height of the cube, so h = b/2. Which means b = 2h.

The cube is made of 6 square pyramids with the same base and height. Therefore, each pyramid has 1/6 the volume of the cube. So the volume of each pyramid is b³/6.
