The answer must be

since the triangular pyramid has 4 faces and each has an area of 30

we should multiply that by 4 , so :
Probabilities are used to determine the chances of selecting a kind of donut from the box.
The probability that Warren eats a chocolate donut, and then a custard filled donut is 0.068
The given parameters are:



The total number of donuts in the box is:


The probability of eating a chocolate donut, and then a custard filled donut is calculated using:

So, we have:

Simplify

Multiply

Divide

Hence, the probability that Warren eats a chocolate donut, and then a custard filled donut is approximately 0.068

Step-by-step explanation:
standard form is given by Ax × By = C
hence the answer would be
5x + 8y = 24
comment if you still have any doubts :)
Area = side * side
Area of the square = 6 1/9 * 6/1/9
= 36 1/81
