To solve the problem step-by-step, we will follow these calculations: ### Step 1: Convert the edge length from picometers to centimeters. The edge length of the unit cell is given as 288 pm (picometers). We need to convert this to centimeters. \[ \text{Edge length} = 288 \, \text{pm} = 288 \times 10^{-10} \, \text{cm} \] ...
