Data:
m (mass) = ?
d (density) = 7.87 g/mL
v (volume) = 3.00cm*4.00cm*1.00cm = 12 cm³ = 12mL
Note: 1 cm³ = 1 mL

Formula:
[tex]d = \frac{m}{v} \to\:m = d*v[/tex]

Solving:
[tex]m = d*v[/tex]
[tex]m = 7.87 g/\diagup\!\!\!\!\!m\diagup\!\!\!\!\!L * 12\diagup\!\!\!\!\!m\diagup\!\!\!\!\!L[/tex]
[tex]\boxed{\boxed{m = 94.44\:g}}\end{array}}\qquad\quad\checkmark[/tex]
