## How do you find the density of a triangular prism?

If we want to calculate density, we simply cover up density in the triangle and see what remains. Since mass is above volume, we divide mass by volume to get density.

## How do I find the density of a rectangular prism?

Use the object’s mass and volume to find density. Density equals mass divided by volume. Simply make this calculation, and you have found the object’s density. Make sure to label your final calculation with the proper units: g/cm^3.

## What is the formula to find the total surface area of a triangular prism?

The formula of the surface area of a right triangular prism is (Length × Perimeter) + (2 × Base Area) = (s1 s 1 + s2 s 2 + h)L + bh where b is the bottom edge of the base triangle, h is the height of the base triangle, L is the length of the prism and s1 s 1 , s2 s 2 are the two edges of the base triangle.

## How do you construct a parallelogram with two sides and a diagonal?

Construct a parallelogram when one side and two diagonals are given – example

- Construct line segment AB of length 7 cm.
- From point A, mark an arc taking 5 cm as radius.
- From point B, mark an arc taking 4 cm as radius.
- Extend AO and BO.
- Similarly mark an arc on extended ray BO of radius 4 cm.
- Join AD, DC and BC.

## What is the formula to calculate the density of an object?

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

## What are 3 ways to find density?

Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters. Multiply these three measurements to find the volume in cubic centimeters. Divide the object’s mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.

## How to calculate the height of a parallelepiped?

The height of the parallelepiped is 4 inches. Find the cost of painting its walls from outside at a cost of INR 1.5 per square inch. Solution: We need to find the lateral surface area first, therefore; LSA = Perimeter of base × height

## How to write formula for volume and area of parallelepiped?

Suppose, length = a, width = b and height = c, we can write the formula of volume, surface area and length of the diagonal of the rectangular box as; The base face of a parallelepiped has opposite sides measuring 5 inches and 10 inches. The height of the parallelepiped is 4 inches.

## Which is an example of a parallelepiped formula?

A common example you can see in real life is the shoe box, which has a rectangular shape. Volume of Rectangular Parallelepiped = Surface Area × Height. Here, the surface area is equal to the area of rectangle = Length × Width. Therefore, the volume becomes; V = Length × Width × Height.

## How to calculate the volume of a parallelogram?

For a given parallelepiped, let S is the area of the bottom face and H is the height, then the volume formula is given by; V = S × H Since the base of parallelepiped is in the shape of a parallelogram, therefore we can use the formula for the area of the parallelogram to find the base area.
