Answer 1

39 ft²

Explanation:

Surface area of square pyramid:

Surface area of square pyramid = lateral surface area+ base area

s = 3 ft

l = 5 ft

`\sf \boxed{\text {\bf Surface area of square pyramid = $2sl +s^2$ }}`

s - side of the base square

l- slant height

Surface area = 2*3*5 + 3*3

= 30 + 9

= 39 ft²
