Calculate the volume and standard deviation of the volume of the triangular prism

Question

The length l = 120.236m +/-0.025m, the width b = 42.524m +/- 0.014m, the height = 55.632m +/- 0.018m.

Calculate the volume and standard deviation of the triangular prism.

Answer 1

volume is area of the triangular base * height

variance is the sum of the square of the deviations/3

standard deviation is the square root of the variance
