A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density​

The density of the prism is 0.453 kilograms per cubic meter.

Step-by-step explanation:

Let suppose that mass in the prism is uniformly distributed. Then, the definition of density (), in kilograms per cubic meter, is defined by the equation below:

(1)

Where:

- Mass, in kilograms.

- Volume of the right angle triangle prism, in cubic meters.

Besides, the volume of the right angle triangle prism is:

(2)

Where:

- Breadth of the base, in meters.

- Height of the base, in meters.

- Length of the base, in meters.

If we know that , , and , then the density of the prism is:

The density of the prism is 0.453 kilograms per cubic meter.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
