Volume is length x width x height.

Calculate the volume of each rectangle and add them together.

7.5 x 7.5 x 3.55 = 199.6875

7.5 x 3.55 x 3.55 = 94.51875

Volume = 94.51875 + 199.6875 = 294.21 cubic meters

OleMash [197]

Answer:

diamerer of the hair (t)  3.11 X 10^{-5} m

Step-by-step explanation:

The first dark spot is at the zero location where the glass plates touch. To find the number of dark fringes after first dark fringe, divide 12 cm by 0.75 mm (.075 cm)

12/.075 = 160.0

total number of additional bright fringe is 156 because there is no further portion for extra dark fringe.

diamerer of the hair (t) can be derived as

2nt = (m + .5)*wavelength

2(1.52)(t) = (160.5)(589.3 X 10^{-9})

t = 3.11 X 10^{-5} m
