No. By definition, the lateral faces of a pyramid are triangular.No. By definition, the lateral faces of a pyramid are triangular.No. By definition, the lateral faces of a pyramid are triangular.No. By definition, the lateral faces of a pyramid are triangular.

Triangular.A pyramid has triangular faces

Lateral faces are the number of faces excluding the base. Since the square is the base, the other 4 sides will each be touching a lateral face to form a square pyramid (or it wont be a pyramid). So, there are 4.

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.

Total surface area= 1/2 times the perimeter of the base times the slant height plus the area of the base Lateral surface area= 1/2 times the perimeter times the slant height

It is the lateral area (which is 1/2 the perimeter multiplied by the slant height), plus the area of the base.

If it is a regular pyramid you need to find out the base perimeter, multiply it by the height of the sides (when considered as triangles) and divide by two. The height of the side can be found using Pythagoras's formula if you know the height of the pyramid and the length of a side. The side height of a pyramid is also known as the slanted height or L in a formula. Formula:permiter of base x L(side height) ( P of B)(L) p x L(slant) ----------------------------------------- = --------------------- 2 2 Good luck!

The lateral sides get taller and narrower. (:

The lateral of a pyramid is a line commencing from the tip, down it's face and finishes at the middle of one of the base's sides. The lateral area of a pyramid is one of it's sloped faces, or outer wall if you wish.
