Answer:
60
Step-by-step explanation:
We have to find least common denominator for these fractions or we just have to find the least common multiple for 15, 6 and 4
In order to find the least common multiple, we have to represent these numbers as factors of prime numbers:
15 = 3 * 5
6 = 2 * 3
4 = 2 * 2
Least common multiples will be common factors (considering that there are no more than of them in other numbers) and the uncommon factors. Then, we can write that:
2 * 2 * 3 * 5 = 60 (there are two 2's, one common 3 and an uncommon 5)
The denominator will be 60 for the least common multiples.
The formula for volume is Length x Width x Height.
So when you apply this formula to these questions the answers should be:
#7. 3x4x2 = 24
#8. 2x4x1 = 8
#9. 3x4x2 = 24
#10. 4x3x1 = 12
I hope this helps!
