Question

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

Answer 1

Answer:

Surface area of square pyramid = $55cm^{2}$

Step-by-step 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 = $55cm^{2}$
