Final answer:
To find the total surface area of a regular geometric solid, use the formula: Total Surface Area = Number of Faces × Area of Face.
Step-by-step explanation:
To find the total surface area of a regular geometric solid, we can use the formula: Total Surface Area = Number of Faces × Area of Face. Given that the area of one face is 15.75 square units, we need to determine the total surface area. In this case, the number of faces is not provided, so we cannot determine the exact value. However, we can use the information given to calculate the number of faces and then find the total surface area. Let's assume that there are n faces:
Total Surface Area = n × 15.75
From the given options, the value closest to the total surface area should be selected. Without the actual value of n, we cannot determine the exact total surface area.
