What is the volume of the triangular prism to the nearest whole unit?

Step-by-step explanation:

You need to use the following formula to calculate the volume of Triangular prism:

Where "a" is  the area of one triangular base and "h" is the height of the triangular prism.

Calculate "a" with this formula:

Where "b" is the base of the triangle and "H" is the height.

In this case:

Then, substituting values, you get that the area is the following:

Finally, you must substitute values into the formula for calculate the volume of the triangular prism, and you also must substitute , which is its height:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
