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 ,

$\text{Surface area of pyramid }=\frac{1}{2}\times perimeter\times \text{ slant height}$

$\text{ Since, perimeter of square }=4\times side\\=4\times 1212\\=4848 cm$

Now,

$\text{ Surface area of pyramid }= \frac{1}{2}\times 4848\times 1818\\\\\text{ Surface area of pyramid }=4406832\text{ square cm}$

Hence, surface area of pyramid = 4406832 square cm.
