What is the volume of the triangular prism? A triangular prism. The base of the triangular face is 5.4 centimeters and the heigh
IceJOKER [234]

Answer:

The volume of the triangular prism is <em>51</em><em>.</em><em>84</em><em> </em><em>cm</em><em>^</em><em>3</em>.

Step-by-step explanation:

The formula of the volume of a prism is:

V = Ah

where:

V = Volume of prism

A = Area of uniform cross-section or base of prism

h = Height of prism = 6 cm

We can substitute the information given in the problem into this formula.

To find A, we need to find the area of the triangular base.

A = bh / 2

where:

b = Base of triangle = 5.4 cm

h = Perpendicular height of triangle = 3.2 cm

We can substitute the information given in the problem into this formula.

A = ( 5.4 × 3.2 ) / 2

A = 17.28 / 2

A = 8.64 cm^2

Substitute the value of A into the original volume of a prism formula with the other information given in the problem.

V = Ah

V = ( 8.64 ) ( 6 )

V = 51.84 cm^3

What is 3 divided by 39 (step by step for branliest!
Usimov [2.4K]

Answer:

39 / 3 = 13

Step-by-step explanation:

first find out how many times 39 goes into 3 by writing the multiplication facts of 3.

3x1=3             3x8=24

3x2=6            3x9=27

3x3=9            3x10=30

3x4=12           3x11=33

3x5=15           3x12=36

3x6=18           <u>3x13=39</u>

3x7=21           3x14=42

You use 3x13 because 3x13 equals to 39 and that is our dividend.

The answer is 13
