Question

Find the Volume of each Polyhedron below:

Answer 1

To find volume of a triangular pyramid you need to apply this formula:

A*H/3

First you have to find the area of the triangular face using 1/2(b*h)

1

__ (6)(8)

2

The area of the triangle is:

1

_. (48)

2

A=24

The solution of the area is 24.

Next you plug in A for the formula.

24*H/3

Height is given.

H=10

Then you plug in the height in the formula:

24*10/3

240/3

The solution should turn out to be 80.

ANS: 80

Answer 2

Determine area of triangular face, (1/2)bh.

Multiply by the length.
