Asquare pyramid has base edge length 14 m. the height of the pyramid is 24 m. find the surface area of the square pyramid. use pencil and paper. draw a net for the figure and find the surface area.

The total surface area is 896

Step-by-step explanation:

The square pyramid is a solid with square base and symmetric 4 triangular faces.

Given that the square base is 14 m and height is 24 m.

The apex of pyramid, center of square and center of any edge of square make a right angled triangle.

Let that height if triangular face be "x".

by pythagoras theorm ,

x = 25 m

the area of square base is

the area of each triangular side is

such are 4 triangles, thus

Thus the total surface area is 196 + 700 = 896

b. x- 48 =120
