- Determine the density, and the uncertainty in the density, of a rectangular prism made of wood. The dimensions of the prism (length L, width W, height H) and mass M were measured to be: L W = H M = (89+1) mm (56±1) mm (151 ± 1) mm (741 ± 5) g To determine the uncertainty of the density, follow the procedure explained in the lab manual in the section devoted to uncertainties. Which term makes the largest contribu- tion to the total uncertainty? Hence, if one wants to improve the overall precision of the measurement of the density, for which measurement would it be best to try to reduce the uncertainty?In the calculation of the area of the same square measuring:5.0 cm ± .05 cm by 5.0 cm +.05 cm,What is the + error on the calculation of the area of the square?(a) What is the area and uncertainty in area of one side of a rectangular plastic brick that has a length of (21.41 0,2) cm and a width of (9.5 10.1) cm?
