1 pound = 453.59237 grams
so 5.26 pounds = 2385.896 grams
1 inch cubed = 16.387064 centimeters cubed
so 14 inches cubed= 229.418 cm cubed
D=M/V
D=2385.896/229.418
D=10.39 gram / cubic centimeter

1 cm3 = 1 ml. Therefore, 17.52 mL has a mass of 0.7857g/mL x 17.52 mL which is 13.7g.

V = mass/density = 7.25g / 0.7857 g/mL = 9.22 mL
