HELP AND PLS EXPLAIN AND ILL MARK BRAINLIEST PLSS I'M CONFUSED AND NEED HELP FAST ​

Answer 1

Answer:

Okay so what you do is multiply 6*9*4.5 together and that'll give you 243 as the volume of the prism. I'm not sure what it is in decimal. I'm guessing 24.3

I'm so sorry if this is incorrect.

Have a great day! <3

Answer 2

Answer:

121.5 ft^2

Step-by-step explanation:

To find Volume of Triangular prism, find the area of the triangular shape first.

Step 1:     6 x 4.5 = 27(square)

Step 2:   27 x .5 = 13.5(triangle)

13.5 x 9(the width) = 121.5

Because volume is length x width x height.

The height and length is 6 x 4.5 in this problem.

Note :  I did "x.5 " because I needed to divide 27 by two to get a triangle. Since a triangle is half a square.  Dividing by 2 and multiplying by .5 are the same thing.

Example: 20 x .5 =10 or 20/2 =10
