4ft X 1/5 by 6 ft X 1/5= 4/5ft by 1 1/5 ft= 0.8 ft by 1.2 ft
0.8 foot × 1.2 feet
Answer:
10*10*12 = 120 ÷ 3 = 40
Step-by-step explanation:
The formula to find a pyramid's volume is
V = (length 'times' width 'times' height, divided by 3)
Answer:
9.5
Step-by-step explanation:
the numbers go up by 1.5
so, 7.5 + 1.5 = 9
Answer:
v=52.5
Step-by-step explanation:
the angle is right so both of the sides should equal 90 degrees
90-(minus)37.5 is 52.5
Let's say you had the two numbers 12 and 3. They multiply to 12*3 = 36. Applying the square root leads to sqrt(36) = 6.
Therefore, the geometric mean of 12 and 3 is 6.
In general, the geometric mean between two numbers x and y is sqrt(x*y). You multiply first, then apply the square root.
If you are working with 3 numbers, you multiply them out like before, but you instead apply the cube root. With 4 numbers you multiply like normal, but this time you would use a fourth root, and so on. With n numbers, you'll apply the nth root.
