A solid right pyramid has a square base. The base edge length is 2cm longer than the height of the pyramid. If the height is 6cm the volume of the pyramid is what

Okay. So we know that the bar edge length is 8 cm (6+2) and the height is 6 cm ...

And a pyramid's volume is 1/3 of a prism's volume.

If the base is square and both sides are 6 cm, the area is 36 cm^2. Then you multiply that area by the height: 288 cm^3.

BUT you have divide that by 3, because a pyramid's volume is 1/3 of a prism's volume: 288/3 = 96 cm^3.

Answer: 96 cm^3
