For Geometric Mean, first we multiply the numbers together and then take a square root since there are two numbers).
Therefore,
6 x 10 = 60
Then we take the square root
√60= 7.746
7.746 as an integer is 8, as the fractional part of 0.746 is greater than 0.5, we therefore make it 1 as a rule and add to the whole number, to make it 8.
I hope this helps, please mark as brainliest answer.
I think it is 64 just multiply 4 times 4 times 4 because of the sides and to find volume you need to multiply the sides and the height so it should be 64.
