Answer:

Volume of a triangular irregular prism=1300.16m^3 = 1300m^2

Volume of a rectangular prism two answers = 1197m^3 or 1233m^3

Step-by-step explanation:

With rectangular prism two answers we need the rectangle surface area first

A = 9 m x 19 m = 171m

or A = 7 m x 19m

The rectangle prism could be 1197m^3 or 1233m^3

depending how big the rectangle is as we calculate that first then multiply by depth. If we had the direction of measurement of the base we would just get one answer and not two.

Rectangular prism A = 171sq

V = 1197m^3 = (171sq x 7)

or V= 1233m^3 = 137sq x 9

If the prism is a irregular prism we add the surface area's

V = (a+b+c)B/3

V = (7x19)(9x7) (9x19) x B = 133 + 63 + 197 x 197 = 3900.5/3 =1300.16

Given that the half life of 3H is 12.3 years.

The amount of substance left of a radioactive substance with half life of $t_{ \frac{1}{2} }$ after t years is given by

$N(t)=N_0\left(\frac{1}{2} \right)^{ \frac{t}{t_{\frac{1}{2}} }$

Therefore, the number of years it will take for 18% of the original tritinum to remain is given by

$18 \% = 100 \% \left(\frac{1}{2} \right)^{ \frac{t}{12.3}} \\ \\ \Rightarrow\left(\frac{1}{2} \right)^{ \frac{t}{12.3}} =0.18 \\ \\ \Rightarrow\frac{t}{12.3}\ln\left(\frac{1}{2} \right)=\ln0.18 \\ \\ \Rightarrow\frac{t}{12.3}= \frac{\ln0.18}{\ln\left(\frac{1}{2} \right)} = \frac{-1.715}{-0.6931} =2.474\\ \\ \Rightarrow t=2.474(12.3)=30.4$

Therefore, the number of <span>years that the time could be read at night is 30.4 years.</span>
