Aright square pyramid is pictured below. if l is 15 cm and x is 18 cm, what is the surface area of the pyramid?

The surface area of square pyramid is 953.64  cm² .

Step-by-step explanation:

Given as for a square pyramid :

The height of pyramid = l  = 15 cm

The base of square pyramid = x = 18 cm

Now,

The surface area of square Pyramid =

or , The surface area of square Pyramid =

Or, The surface area of square Pyramid =

Or,  The surface area of square Pyramid = 324 + 36 ×

or,  The surface area of square Pyramid = 324 + 36 × 17.49

Or , The surface area of square Pyramid = 324 + 629.64 = 953.64 cm²

Hence The surface area of square pyramid is 953.64  cm² .  Answer
