Step-by-step explanation:
Part A) What is the height of the base?
we know that
The volume of the triangular prism is equal to
where
B is the area of the triangular face
L is the length of the prism
we have
substitute the given values
solve for B
Find the height of the base
we know that
The area of triangle i equal to
solve for h
Part B) What is the approximate amount of cardboard used to make the candy box?
we know that
To find out the the approximate amount of cardboard used to make the candy box, determine the surface area of the triangular prism
The surface area is equal to
where
B is the area of the triangular base
P is the perimeter of the triangular base
L is the length
we have
Find the perimeter of triangle P
substitute
