$52.324
Step-by-step explanation:
Given:
The volume of a prism with equilateral triangular cross-section is 270cm³.
Length of the prism =
cm
To find:
The length of the side of the equilateral triangular cross-section.
Solution:
Formulae used:
Area of an equilateral triangle is

Where a is the side length of equilateral triangle.
Volume of prism is

Where, B is base area and h is the height of the triangular prism.
Cross section of the prism is an equilateral triangular so the base area of the prism is
sq. cm.
The volume of the prism is




Divide both sides by 7.5.




It takes only positive value because the side cannot be negative.
Therefore, the length of the side of the equilateral triangular cross-section is 6 cm.
Both are correct they just chose a different variable to solve for first. they will both get correct answers if they do the rest correctly.
Answer:
Step-by-step explanation:
They are about 3 meters away from each other
and the correct area is 15.5-12 and the correct answer is 3.5 meters apart
