Find the volume of a triangular pyramid a=8 h=8.54

The volume of the given triangular pyramid is 22.773 cubic units.

Step-by-step explanation:  We are given to find the volume of a triangular pyramid with the following dimensions :

area of the triangle base, a = 8 sq. units

and

height of the pyramid, h = 8.54 units.

We know that

the area of a triangular pyramid with triangle base area a and height h is  given by

Therefore, the volume of the given triangular pyramid is given by

Thus, the volume of the given triangular pyramid is 22.773 cubic units.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
