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

Step-by-step 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:

$h=\frac{4.9in*2.54cm}{1cm}=12.44cm$

$w=\frac{2.3in*2.54cm}{1cm}=5.84cm$

4. Convert milimeters to centimeters:

$d=\frac{8mm}{10}=0.8cm$

4. Then, the volume is:

$V=(12.44cm)(5.84cm)(0.8cm)=58.11cm^{3}$
