Final answer:
The formula to calculate the total enclosed space of Firm 1's structure is the formula for the volume of a cylinder, which is V = πr^2h.
Step-by-step explanation:
The formula that can be used to calculate the total enclosed space of Firm 1's structure is the formula for the volume of a cylinder. A cylinder is a three-dimensional shape that consists of two circular bases and a curved surface connecting the bases. The formula for the volume of a cylinder is V = πr^2h, where V represents the volume, π is a constant (approximately 3.14), r is the radius of the circular base, and h is the height of the cylinder.
