Madden Liu · Answer 1

Given:

Density = 1.2 viruses per square millimeters

Area = 2,826 square millimeters

Density = Number of viruses / Area

Number of viruses = Density * Area

Number of viruses = 1.2 viruses / square mm * 2,826 square mm

Number of viruses = 1.2 viruses * 2,826

Number of viruses = 3,391.2 viruses
