Question

How do I calculate volume if there are 3 numbers?

Community Answer

Just times all the numbers together. Once you do, the number you get will be your final answer cubed.

Question

I need to find the height of a display box shaped like a triangular prism that holds 875 cm3. The bottom of the box measures 35cm by 10 cm. How do I find this?

Donagan

Top Answerer

Divide the volume of the prism by the area of the triangle.

Question

How do I calculate the surface area of a hexagonal prism?

Donagan

Top Answerer

Assuming you know the length of each side, multiply the full perimeter by the height. If you need to include the surface area of the two ends of the prism, calculate the area of a hexagonal end, double it, and add that to the lateral surfaces calculated above.

Question

How do I calculate the surface area of a triangular prism?

Community Answer

To calculate the surface area, you need to take the sum of the areas of each side. There will be five sides to a triangular prism -- three rectangles and two triangles. Use the formula A=0.5(base*height) to get the area for each triangle. For the rectangles, simply use width*length. After you have the areas for each individual face, add them together. This will give you the total surface area.

Question

A triangular prism has a volume of 350 cubic meters. If the dimensions are tripled, what is the volume of the new prism?

Donagan

Top Answerer

The new volume is nine times the old volume (three dimensions, each tripled).

Question

How many bases are in a triangular prism?

Community Answer

The top and bottom, which are triangles, are bases. The three rectangles are called lateral faces. A triangular prism has five faces consisting of two triangular bases and three rectangular lateral faces. A base is also a face.

Question

What are the formulas to find volume, area and perimeter?

Community Answer

To find volume, find the area of the base, and multiply it by the height. To find the area, if it is a triangle, it is Base x Height divided by 2. If it is a square or rectangle, Base x Height. If it is 3D, add all the sides together.

Question

Is it possible to find area of a cylinder another way that does not involve triangles?

Community Answer

Yes, find the circumference of the circle and multiply it by the height, then find the area of the circles (A=2 π r) or (A= π d) and add them together. Don't forget there are two circles.
