Final answer:
The volume of all the iPhones ever made is 92,150.16 m³.
Step-by-step explanation:
To calculate the volume of all the iPhones ever made, we need to find the volume of a single iPhone and then multiply it by the total number of iPhones produced. The volume of a rectangular prism (such as an iPhone) is found by multiplying its length, width, and height. In this case, the dimensions of an average iPhone are given as 143.6 mm x 70.9 mm x 7.7 mm. To convert these dimensions to meters, we divide each dimension by 1000:
Length: 143.6 mm ÷ 1000 = 0.1436 m
Width: 70.9 mm ÷ 1000 = 0.0709 m
Height: 7.7 mm ÷ 1000 = 0.0077 m
Now we can calculate the volume:
Volume of a single iPhone = 0.1436 m x 0.0709 m x 0.0077 m
= 0.0000767918 m³
Finally, to find the volume of all the iPhones, we multiply the volume of a single iPhone by the total number of iPhones produced:
Volume of all iPhones = 0.0000767918 m³ x 1.2 billion
= 92,150.16 m³
