The volume of this triangular prism is 247.5 cubic inches. what is the value of t?
t = __ inches

Volume of a triangle is 1/2 base x height x length.

Using the given information we can find t:

247.5 = 1/2(5)(t)(11)

Simplify:

247.5 = 2.5(t)(11)

247.5 = 27.5t

Divide both sides by 27.5:

t = 247.5 / 27.5

t = 9

Step-by-step explanation:

The formula of a volume of a prism:

B - area of a base

H - height

In the base is the triangle.

The formula of an area of a triangle:

b - base

h - height

We have V = 247.5 in³, b = 5 in, H = 11 in and h = t.

Therefore:

Put them to the formula of a volume:

             divide both sides by 27.5

i am thinking c. sorry if im wrong .

step-by-step explanation:

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
