How to Calculate Dot Product of Two Vectors?

[IHave]

Homework Statement

obtain the dot product of the two vectors F= 10i + 6j - 3k lb and B= 6i -2j ft

Homework Equations

F dot B = FxBx + FyBy + FzBz
x is for the x components
y is for the y components
z is for the z components

The Attempt at a Solution

F dot B = (60 + -12 + 0)
I ended up with 48 lb-ft. I really just want someone to check my work. thanks
