3 x 3 x 3 = 27
Each of the 3 layers has 3 x 3 cubes
All minute cubes on bottom layer touch bottom of box
All minuscule cubes (except for middle cubes) of middle and top layers, touch sides of box
So 2 cubes don't physically contact bottom or side of box
Answer: 25
Answer:
7 is the greatest comman factor of 28 and 49
Answer:
10
Step-by-step explanation:
Means back the numbers into multiples of several small numbers
Like:; 1. We take LCM of 40
Just break into multiples of small number
40= 2×2×2×5
2. We take LCM of 50
50= 5×5×2
So LCM for 100 is 2×2×5×5
after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)
Then write the the single number in place of two multipled numbers
Like:; 2×2 is written as 2 // 3×3 is written as 3
So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)
write pairs in single number 2×5
And so we get 2×5=10
So we find root of 100 that is 10
Log 10 100 =2
Basically, we have to know how to solve for x in this equation:
10^x = 100
For log3 = 9 we have to solve for x in this equation:
3^x = 9
Therefore, x = 2
