The logarithm of a function log a = x is also expressed as 10^x = a. In this case, we are given log (x) = -0.123. Hence the equivalent function is 10^-0.123 = x; x is equal to 0.7536. the answer to this problem is 0.7536.

The volume of a prism is:

Where, B is the base area and h is the height.
A right prism has a volume of 65 cubic inches.

The height of prism is increased by a factor of 20. So, the new volume is:




The volume of the new prism is 1300 in³.
Therefore, the correct option is B.
