Suppose the volume V of some object hap-

pens to depend on time t according to the

equation V (t) = At3+B/t

, where A and B are

constants. Let L and T denote dimensions of

length and time, respectively.

What is the dimension of the constant A?

1. L2/T

2. L/T3

3. L3/T3

4. L/T

5. L3

· T3

the 3 is actually a cubed as is the 2
