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}
