Answer 1

Answer:

The surface area is $0.64\ m^{2}$

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces.

so

$SA=b^{2}+4[\frac{1}{2}(b)(l)]$

we have

$b=0.4\ m$

$l=0.6\ m$

substitute the values

$SA=0.4^{2}+4[\frac{1}{2}(0.4)(0.6)]=0.64\ m^{2}$
