Question

Find the surface area of a square pyramid with base edges
of 5 cm and a slant height of 3 cm.

Answer 1

Surface area of square pyramid =
`55cm^(2)`

Explanation:

Let, b is the base edges and s is the slant height

According to given condition:

b = 5 cm

s = 3 cm

Find out:

Surface area of square pyramid = ?

Formula:

Surface area of square pyramid =
`b^(2) + 2bs`

Solution:

Surface area of square pyramid =
`b^(2) + 2bs`

Surface area of square pyramid =
`5^(2) + 2(5)(3)`

Surface area of square pyramid =
`(25+ 30 ) cm^(2)`

Surface area of square pyramid =
`55cm^(2)`
