Question

) a smart phone has dimensions of 4.9 inches (height), 2.3 inches (width) and 8.0 millimeters (depth). what is the volume of the smart phone in cubic centimeters? (1 in = 2.54 cm)

Answer 1

Answer: 58.11 cm³

Explanation:

1. The volume can be calculated with the following formula:

`V=h*w*d`

Where l is the lenght, w is the width and h is the heigth of the smartphone.

2. You know that the dimensions are:

`h=4.9in\\w=2.3in\\d=8mm`

3. Convert the height and the width from inches to centimeters, as following:

`h=(4.9in*2.54cm)/(1cm)=12.44cm`

`w=(2.3in*2.54cm)/(1cm)=5.84cm`

4. Convert milimeters to centimeters:

`d=(8mm)/(10)=0.8cm`

4. Then, the volume is:

`V=(12.44cm)(5.84cm)(0.8cm)=58.11cm^(3)`
