Set up a proportion: 3/10= x/80. Then if you multiply 10 by 8, you get 80 on both sides, But, If you do it to the top, you also have to do it to the bottom, so the anser is 3 x 8 , or 24.
Answer:
Step-by-step explanation:
In order to calculate the volume of a triangular prism you need 2 things:
The triangles area and the prism's height.
Any prism's volume can be calculated by multiplying its base area with its height.
The Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a = 
When you have the prism's base area (
) you just have to multiply:
(V = volume)

Answer:
3 inches is 25 percent of a foot
4 inches is 33.33 percent of a foot
6 inches is 50 percent of a foot
9 inches is 75 percent of a foot
Step-by-step explanation:
The first thing we need to do to solve this problem is to convert our measurements in feet to inches.
1 foot = 12 inches
we can now find our percentage with ease since we are now making comparisons, using the same unit of measurement as a reference.
To get the percentage of which 3 is of 12, we simply perform the following operation: We divide 3 by 12 then multiply it by a hundred percent.
(3/12) X 100 = 25 percent.
3 inches is 25 percent of a foot
Similarly,
4 inches = (4/12) X 100 = 33.33 percent of a foot
6 inches =(6/12) X 100 = 50 percent of a foot
9 inches = (9/12) X 100 = 75 percent of a foot
