Answer:
3200 cm^3
Step-by-step explanation:
1. Calculate the sides of the right triangle to get the height
We know that side c = 26 and the shortest leg is 10 cm (20cm/2) because this right triangle splits the 20cm in two)
a = 10, b = 24, c = 26
2. Use the formula for the volume of a square pyramid now that you have the height (which is b)
V = 3200
I hope this helped! :)

Answer:
Step-by-step explanation:
Probability refers to chance of happening of some event.
Conditional probability is the probability of an event A, given that another event B has already occurred.
denote the two boxes.
In box :
No. of black balls = 1
No. of white balls = 1
In box :
No. of black balls = 2
No. of white balls = 1
Let B, W denote black and white marble.
So, probability that either of the boxes is chosen is
Probability that a black ball is chosen from box =
Probability that a black ball is chosen from box
To find:probability that the marble is black
Solution:
Probability that the marble is black =
