The equation to find the volume of a pyramid is V=
3.) V=
→ Multiply the top V=
→ Divide by 3 V=
4.) V=
→ Multiply the top V=
→ Divide by 3 V=59.904 or V=59.9
5.) Since you need to find h you put the V value in and keep the h value blank. 1,350=
→ 1,350=
→ Multiply 3 by both sides 3×1,350=×3 → 4,050=225×h → Divide 225 from both sides 4,050÷225=225×h÷225 → 18=h

Answer: OPTION A
Step-by-step explanation:
Descompose the number 20 into its prime factors:
Because, by definition:
Then, you must rewrite 2²*5 inside of the square root, as following;
Simplify as following:
Keeping on mind that , then:
Note:
Then:
Therefore, as you can see the answer is the option A
