Explanation:

Step1: Calculate base square area

$\text{Area}_{\text{square}} = 5 \times 5 = 25$ square inches

Step2: Calculate one triangle area

$\text{Area}_{\text{triangle}} = \frac{1}{2} \times 5 \times 6 = 15$ square inches

Step3: Calculate total triangle area

$\text{Total}_{\text{triangles}} = 4 \times 15 = 60$ square inches

Step4: Sum base and triangle areas

$\text{Total Surface Area} = 25 + 60 = 85$ square inches

Answer:

85 square inches
