Triangular Prism. It has 3 rectangular faces and 2 triangular bases
The answer is: [B]: " 3.99 * 10⁻⁶ " .

Note:
______________________________________________
We are given the following answer choices, and we are asked which one is the "smallest number" :
_______________________________________________
[A]: 4.4 * 10⁻⁵
_________________________________________
[B]: 3.99 ⋅ 10⁻⁶
______________________
[C]: 2.6 ⋅ 10²
______________________
[D]: 1.85 ⋅ 10³
_______________________
We can rule out answer choices: [C] and [D]; since these values, essentially "direct us" to move the decimal point FORWARD "2 places" and "3 places", respectively; whereas choices [A] and [B] essentially "direct us" to move the decimal point BACKWARD "5 places" and "6 places" respectively. Note that all values given in the answer choices are written in proper "scientific notation" —that is, beginning with a "single integer followed by (a) decimal point(s) and then additional digits (when needed). So, the answer choice that essentially "directs us" to move the decimal point BACKWARD "6 places" —

→ Answer choice: [B]: " 3.99 * 10⁻⁶ " ;

is the smallest value ; and as such, the correct answer.

Answer:
10u²
Step-by-step explanation:
The formula for area of a triangle is b*h/2. When you plug in the numbers, you get 10. Hope this helps!
A = s^2
A = 40
40 = s^2...by taking the square root of both sides, u eliminate the ^2
sqrt 40 = s
6.32 = s <===
