The volume of titanium is 20.86 cubic inches
<em><u>Solution:</u></em>
The volume is given by formula:
From given,
Density of titanium = 4.51 
Mass = 3.4 lb
Let us convert the mass to grams
1 pound = 453.592 grams
Therefore, 3.4 pound is equal to:
Now substitute the values into formula:
Let us convert cubic centimeter to cubic inches
1 cubic centimeter = 0.0610237 cubic inches
Therefore,
Thus volume of titanium is 20.86 cubic inches
Answer:
Given that:
Susan spent on supplies = $17.75
Earning of june = 24 * $3.25
