Question

The pyramid shown has a square base that is 1212 centimeters on each side. The slant height is 1818 centimeters. What is the surface area of the pyramid?

Answer 1

Answer : Surface area of pyramid = 4406832 square cm.

Explanation :

Since we have given that

Side of square base = 1212 cm

Slant height of pyramid = 1818 cm

As we know that ,

`\text{Surface area of pyramid }=(1)/(2)* perimeter* \text{ slant height}`

`\text{ Since, perimeter of square }=4* side\\=4* 1212\\=4848 cm`

Now,

`\text{ Surface area of pyramid }= (1)/(2)* 4848* 1818\\\\\text{ Surface area of pyramid }=4406832\text{ square cm}`

Hence, surface area of pyramid = 4406832 square cm.
