A triangular prism has a height of 18 inches and a volume of 864 cubic inches what is the area of the base of the figure

The answer is B

Step-by-step explanation:

It is given that the formule of volume of prism is V = a × h where a stands for area of cross-section. Then, substitute the following value into the formula :

V = 864 in³

h = 18 in

a = ?

864 = a × 18

Next, you have to make a as the subject by dividing 18 on both sides :

864 ÷ 18 = a × 18 ÷ 18

48 = a

a = 48 in²

Hope this was helpful if not im sry for the answer.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
