of the square pyramid?
9 in
6 in

Answer 1

Answer:The Surface Area of Pyramid is 105 cm².

Explanation:

What is Surface Area of Pyramid?

If “P” is the base perimeter, “l” is the slant height, and “B” is the base area, then the total surface area of the regular pyramid formula is given by (½)Pl + B Square units.

Given:

slant height, l= 8 cm

So, the base Perimeter = 4 x 5

= 20 cm

Now, area of the base = 5 cm x 5 cm

= 25 cm²

Then, surface area of a square pyramid

= 1/2 x slant height x base perimeter + area of base

= 1/2 x 8 x 20 + 25

= 80 + 25

= 105 cm²
