It depends on what the question is: the volume, surface area, colour, smell? Some of these can be answered with the given information , others can't. But since you have not bothered to provide that crucial bit of information about wat is required, I cannot provide a more useful answer.
120
It is 448 square cm.
72 cm square.
It depends on the dimensions of the base and the height (slant or vertical) of the pyramid.
slant height of the pyramid Louvre in Paris=28 meters

You need some information about the height of the pyramid and the formula will depend on whether you have the vertical height or the slant height or the length of a lateral edge.
It is 448 square cm.
The slant height will be 25 cm
429 m
72 cm square.
The volume of a regular pyramid with a square base of 8cm and a slant height of 5 cm is: 64 cm3
This pyramid would have a perpendicular height of 3, a volume of 64 units3 and a slant edge of 6.403
By using trigonometry or Pythagoras' theorem
The slant height of a square pyramid is always perpendicular to the base. It is form the top vertex all the way down to the most center of one side of the base edge.
The height would be The square root of the square of the slant surface length minus the square of the radius of the cone at the base.
It depends on the dimensions of the base and the height (slant or vertical) of the pyramid.
